Accurate evaluation of friction using Metal Forming Tribometer (MFT)Automotive industry continues to develop cars that are lighter, stronger, and cost effective to manufacture using advanced high strength steels (ex. 22MnB5). Hot stamping is used to manufacture vehicle components by pressing steel blank (Al-Si, Zn-Ni coatings) above 900o C between closed dies (H13 steel) to get the final shape (Figure 1A). It is known that Volvo has approximately 40 % of its vehicle weight made of hot stamped steel. High temperatures cause excessive friction and wear between the workpiece and die tools driven by adhesive, abrasive and oxidative wear (Figure ... Read More

Airplanes are the safest mode of transportation. However, recent airplane crashes have raised several doubts about their safety. According to preliminary reports, recent airplane crashes may be related to pylons that were redesigned to accommodate the latest fuel-efficient gas turbine engines (15% to 20%), which operate with low maintenance costs (20% to 30%). The purpose of this study is to understand the engine efficiency mechanisms that triggered this fatal design.
High-temperature tribology is of particular importance in industries where operational efficiency is affected by the exposure of materials and tribological interfaces to elevated temperatures. Various factors like elastic modulus, thermal conductivity, hardness, thermo-mechanical fatigue, diffusion, grain structure and oxidation can largely influence friction and wear at high temperatures, thus making it a multicomponent problem.
This conference is an effort to provide open access to tribology research; to aid industries and academicians pushing the frontiers of material technologies and utilization of such technologies for a more sustainable world.
Solid particles in dusty environments can damage materials and affect dimensional tolerances in variety of industries ranging from gas turbines, helicopter rotor system (aerospace applications), boiler tubes (coal power plants) and wind turbines (renewable energy). Erosion of certain components can reduce operational efficiency of systems and have economic impact.
