Title:
MANUFACTURE OF SLIDING MEMBER
Document Type and Number:
Japanese Patent JPS621851
Kind Code:
A
Abstract:
PURPOSE: To improve the strength and seizing resistance by forming a supersatd. layer of an Al-Si alloy contg. hypereutectic Si on a metallic base material and by depositing Si crystals of a prescribed grain size in the supersatd. layer by heat treatment to improve the adhesion to the base material.
CONSTITUTION: An Al-Si alloy contg. hypereutectic Si is melted. This molten alloy is sprayed on a metallic base material and cooled rapidly to form an Si supersatd. layer. The coated base material is heated and subjected to hot plastic working. Si crystals of 3W20μm average grain size are deposited in the supersatd. layer.
