The purpose of this study was to develop a frictional motion material with excellent corrosion and wear resistance in marine environments by generating surface modification layers obtained by frictional reforming techniques using various fine powders mixed with carrier particles. As one means to achieve this, we constructed a system that simultaneously measures the corrosion and wear resistance characteristics of various frictional-reforming materials in artificial seawater under fretting conditions. Frictional reforming was performed on 18Cr-8Ni austenitic stainless steel using hard fine powders of Ti, TiN, Cr, Cr2N, and Al2O3 mixed with Al2O3 carrier particles. The time variations of the frictional and corrosion resistance of these materials in a 3.5 % NaCl solution under fretting conditions were then evaluated simultaneously. The results showed that stainless steel modified by frictional reforming using a mixture of TiN powder and Al2O3 carrier particles has excellent corrosion resistance. However, its wear resistance may be inferior to that of stainless steel. |
