Outline of Final Research Achievements

This study was conducted to establish the advanced hybrid treatment processes which contribute for improving the functionalities and the energy efficiency of mechanical products. To accomplish the purpose, we comprehensively accumulated the academic knowledge concerning the combination effect of various surface modification and heat treatment methods such as plasma nitriding, gas nitriding, DLC coating, fine-particle bombarding and short-time duplex heat treatment. In the above hybrid treatment processes, each treatment was considered a component and some of the treatments were suitably combined to produce the required functionalities depending on the usage and materials. As a result, we have proposed the processes which can simultaneously improve the friction-wear properties, mechanical properties and fatigue strength of alloy steel and titanium alloy.
