tribology in industry

The coefficient of friction for the copper-steel pairing decreases with an increase of the normal load, increases for higher sliding velocities, and shows no obvious dependency on the number of contact points. Speed had major influence on MRR and tool wear whereas, feed had highest impact on surface roughness. Studies have been conducted on the example of the monoester of maleic acid, esters of tartaric and aconitic acids with hexadecyl alcohol. The results also show that the mechanical and tribological properties of the tested material are comparable with those of traditional alloys, such as some kinds of bronze.    • Lubrication … Composites of crushed shells with polyester resin bond were developed separately for the periwinkle and palm kernel shell samples using mould compression, and the sandpaper prototype was produced using hand-spray method. The results obtained lead to the conclusion that ZnAl 27 alloy satisfies the bearing material requirements. In the early 1960s, there was a dramatic increase in the reported failures of plant and machinery due to wear and associated causes. Tribology in Industry publishes experimental and theoretical papers on all aspects of the science of friction, wear and lubrication. The WVAS (Wireless Vibration Acquisition System) interfaced with MAT Lab software is used to record the amplitudes during the test. AISI 1060 carbon steel for turning process is used to find out best cutting parameters using Analysis of Variance (ANOVA) and Regression Concept. We noted also that the KC810 insert was more suitable for machining of SAE 1030 Carbon Steel; where The best life time was registered (T=228 min). Three different greases were aged in rolling bearings for 30 – 50 % of their predicted life. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) was used to conduct the surface morphological examination of corroded and inhibited alloy specimens. The results of evaluation showed an excellent opportunity of widely usage of the vegetable oils derivatives specially Soy Lecithin (SL) in petroleum industry as multifunctional petroleum additives. A comparative analysis of abrasive sandpaper made from two locally sourced and easily available materials, periwinkle and palm kernel shells was carried out to evaluate their viability as replacements for foreign imported abrasives sandpaper. The wear surfaces were analyzed using scanning electron microscopy and energy- dispersive spectroscopy. Tribology in Industry www.tribology.fink.rs Tribological Behavior of Journal Bearing Material under Different Lubricants S. Baskar a, G. Sriram a a Sri Chandrasekharendra Saraswathi Viswa Mahavidyalaya, Enathur – 631561, Kanchipuram, India. The purpose of this paper is to determine the impact multilayer coatings and cutting parameters on tool wear and temperature at the tool-chip interface for two types of coated carbides (KC810 and KC910 Commercialized inserts) during dry turning operation of carbon steel SAE 1030, in order to determine the ideal parameters and guarantee the best performances of the cutting tools. The experimental correlation of ageing behaviour for Al-Cu-Mg/Bagasse ash particulate composites with 2-10wt% bagasse ash particles produced by double stir-casting method has been investigated. Same technique is utilized in the present case to overcome the problem of frictional wear between two parallel surfaces subjected to high acceleration. The adhesive wear behaviors of samples were carried out using ball on disc type tribometer. The critical condition for the transition between two-body and three-body abrasion was determined from a continuum mechanics model for the penetration of the abrasive particles into the surfaces of the ball and the specimen, coupled with considerations of equilibrium. Ageing temperature has great influence on the hardening characteristics of the Al–Cu–Mg/BAp composite. Further, in order to study the effect of individual parameters statistically on the responses, a widely used statistical technique namely Response Surface Methodology (RSM) and a new technique, Random Forest Regression (RFR) have been applied to these experimental data to model and predict the values of surface roughness parameters. S. Prabhu, P.H. Tribology in Industry www.tribology.fink.rs Investigation of Nanostructured Thin Films Adhesion used to Improve Tribological Characteristics of Hip Prostheses L.L. Focusing on Detroit and its rise, fall and comeback as an automotive powerhouse, Don Cohen from Michigan Metrology discusses how tribology in the automotive industry helps overcome challenges in mass production and automation. The experimental results indicated that the volumetric wear rate increased with increasing load, speed and decreased with increasing the tensile strength, but material property was more effective than other factors.    • Biotribology. Neither melt treatment nor solid state processing (like aging and forging) seems to be altering the wear behavior of the materials drastically. Publisher:    • Wear Fabrication of Aluminum LM13/MoS2/TiO2 hybrid metal matrix composite via stir casting technique was carried out to analyze the wear characteristics at an elevated temperature of 150° C using pin on disc tribometer. Taguchi L18 orthogonal array has been employed for fabrication of composite castings and for conducting the tribological experimentation. This trend is informed by the peculiar mechanical properties of aluminium such as light weight, … The resulting layers were tested in three kinds of soil masses: loamy sand, ligh clay and ordinary clay. In general, friction coefficient increases for a certain duration of rubbing and after that it remains constant for the rest of the experimental time. The first of these is the verification of theoretical statements about the mechanism of action of anti-wear additives. Tribology & Materials for Industry est un laboratoire indépendant Expert dans le domaine de la tribologie, la science des matériaux, les surfaces, interfaces et la simulation numérique. Tribology is the study of lubrication, friction, and wear between surfaces in relative motion. In this research work, an investigation is done to study the effect of cryogenic treatment on 316L SS fabricated using Direct Metal Laser Sintering process. This increases the bearing load and causes changes in the engine oil temperature. In order to do so, a pin on disc apparatus is designed and fabricated. Looking at the industrial progresses as a continuum, speaking of evolutions rather than of revolutions, four time spans can be considered for the four Industrial and Tribologic… It is revealed from the experimentation that the fiber filled composites exhibited better abrasion resistance. The tests are carried out with different load conditions (25, 50 and 75 N) and different number of strokes (420,780 and 1605 strokes). Outcome of the research is a graphical pattern showing the lubricant film thickness required at different positions between the contacting surfaces. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use) and NonCommercial usage of the material (You may not use the material for commercial purposes).    • Nanotribology The MMC pins are prepared with different weight percentage of SiC and Al2O3(10, 15 and 20 %). Hardness test and impact test are also carried out on the MMC samples. The obtained physical and mechanical properties were compared to garnet sandpaper and found to be close to acceptable standards. The results indicate that the composite exhibits an accelerated hardening response compared to the unreinforced matrix alloy at the three selected aging temperatures of 100, 200 and 300 °C. The impact factor (IF), also denoted as Journal impact factor (JIF), of an academic journal is a measure of the yearly average number of citations to recent articles published in that journal. During the abrasive wear experiments it is necessary to know the contact force F between the rotating ball and the sample surface. TEM observations reveal that the addition of bagasse ash particles to the Al–Cu–Mg alloy can speed up the growth rate of precipitates S' (Cu 3 Al 2 , and Al 6 CuMg 4) phases. Present research is an extension of author's previous work in the same. Results show that deposition rate on SS 202 increases with the increase in gas flow rate within the observed range. The experimental results reveal that improved friction coefficient and wear rate is obtained after deposition than that of before deposition. ZDDP (zinc dialkyldithiophosphate) is one of the most commonly used petroleum additives as anti-wear, anti-rust and anti-oxidant but it has some environmental problems, so there is a must to find alternative eco-friendly compounds which can replace some of these conventional used petroleum additives.
