Dersin Amacı
One of the main purposes is to emphasize the importance of the material and energy loss during the wear which is one of the biggest problems in application. It is aimed to introduce the selection of conventional and space technology materials, their application areas, wear mechanisms and prevention methods
Dersin İçeriği
Introduction to Wear, Wear Mechanisms, Friction Concept, Wear and Friction Systems, Analysis of the Worn Surfaces and Introduction of Wear Types, Wear in Material Couples Which have Similar Hardness, Wear in Material Couples Which Have Different Hardness, Effect of Microstructure on Wear, Techniques in Decreasing Friction Coefficient, Materials Properties and Materials Selection for Specific Wear, wear Resistance Increasing Methods, Wear and Friction in Nano Materials, wear in Composite Materials
