Sliding tests at 800°C in air of 25Cr-20Ni stainless steel (heat-resistant steel) and high silicon content stainless steel (high Si content steel) clarified that the high Si content steel has better tribological characteristics. Since work hardening and crystal refinement were shown on the glaze oxide layer of high Si content steel, same mechanism as the previous report of Ni-Cr cast alloy, the layer contributes to good tribological characteristics. On the other hand, hard oxides on the surface layer of heat-resistant steel cause the abrasive wear against the soft area formed by wear particle of base material on the surface layer. In this reason, surface layer was removed and sliding surface got rough.
