Abstract:
In a multilayered sintered sliding member, a porous sintered alloy layer comprising 3 to 10 wt.% of an Sn component, 10 to 30 wt.% of an Ni component, 0.5 to 4 wt.% of a P component, 30 to 50 wt.% of an Fe component, 1 to 10 wt.% of a high-speed tool steel component, 1 to 5 wt.% of a graphite component, and 20 to 55 wt.% of a copper component is integrally diffusion-bonded to a backing plate.

Abstract:
A method of providing a porous surface on a nickel substrate comprising treating the substrate with a flowing stream of gas comprising ammonia or hydrazine at a temperature of at least 4000C, the resultant porous surface comprising pores which are substantially all interconnected and have access to the surface.
Abstract:
The powder consists of at 75% by weight of a base material in the form of a powdered high speed steel (HSS). The powder further comprises up 5 to 25% by weight of an added material in the form of a powder and comprising at least 55% by weight of Fe and 5 to 20% by weight of P.
