摘要: Abstract During the Future Advanced Rotorcraft Drive System (FARDS) program, Aviation Development Directorate (ADD), Applied Technology (AATD), Bell Helicopter Textron Inc., University of Toledo and Aristotle Thessaloniki worked together to perform bearing coating tests. The mechanical properties DLC its steel substrate were determined via nano-indentations a FEM supported evaluation obtained results. fatigue adhesion quantified by perpendicular inclined impact tests respectively, coupled with appropriate finite element method (FEM) calculations. conducted under lubricated conditions for avoiding abrasion caused sliding friction on coated surfaces. In this way, failure during test was mainly affected load, material's film adhesion. effects these factors described an iterative method. Using method, estimated taking into account exercised loads material properties.
