As the result, the depth of cut-in region becomes narrower. Tooth flank out side of rag-wear on the middle of tooth flank near pitch line is polished under high contact stress to become mirror like. At the boundary between the polished flank near pitch line and rag-worn region, the tooth flank curvature has inflection point. Pitting or spalling failure often occurs there due to the high contact stress. FOD also often occurs there. The tooth flank material suffers considerable surface and subsurface fatigue damage. Mirror like polished Contact pressure Slipping region Inflection point of tooth flank curvature (vertical line position in this picture) Pitch point Region of rag-wear Cut-in region Progress of subsurface crack Root Position of max.damage Dedendum The durable-capability of tooth flank material changes with run of gear operation, mainly due to the surface temperature effect induced. Tooth flank damage is often the result of the behavior of positive feed-back system of surface failure whose factor is ESV and trochoidal interference.

It was at the end of the last century that outstanding performance in hot metal rolling was reported of the surface layer of tool reinforced with coarse NbC particles by Plasma-Transferred-Arc (PTA) welding but little has been investigated on the roles of matrix and optimum dispersion of NbC particles. In the present work specimens manufactured by PTA welding using NbC particles with different sizes and different fractions were subjected to hot sliding test against medium carbon steel in order to investigate the roles of matrix and the NbC particles held in the matrix. The result showed that the matrix is reinforced as soon as a small amount of NbC is injected into the welded layer and keeps the constant strength regardless of the increase in the fraction of NbC particles. With the increase in the fraction of NbC particles in the welded layer the performance of the surface increases linearly. In the previous use of coarse NbC powder was recommended but present result showed that the effect does not depend upon the size of NbC powder to be PTA-welded. .H\:RUGV NbC, PTA, reinforced tool, hot wear resistance, optimum size of NbC, reinforcement of matrix Plasma Transferred PTA Arc Welding NbC 50% 1) SUS316L TiC 7,8) 10 2) 15 9) VC NbC 3) VC 2,5) NbC 100 μm 4~6) NbC PTA 1 2 3 * 606-8585 Student, Graduate School, Kyoto Institute of Technology (Gosho-kaido-cho, Matsugasaki, Sakyo-ku, Kyoto-shi, Kyoto 606-8585) 454-0831 1 15 Aisei-hard.
