HIGH STRENGTH HIGH ABRASION RESISTANCE SLIDING MEMBER AND MANUFACTURE

摘要

A sliding member formed of sintered silicon nitride shows improvement in strength and abrasion resistance when substantially all the beta -phase type fine silicon nitride particles present as a main component in the sintered silicon nitride have major diameters not exceeding 60 mu m and aspect ratios of not less than 5 and the aforementioned fine silicon nitride particles have a relative density of not less than 98%.
