Title:
SURFACE PROCESSING METHOD OF ALUMINUM ALLOY WHEEL EXCELLENT AGAINST CORROSION FATIGUE
Document Type and Number:
Japanese Patent JPH0871857
Kind Code:
A
Abstract:
PURPOSE: To provide a surface processing method increasing the fatigue life of an aluminum alloy wheel used for a large vehicle, a superhigh-speed vehicle, or the like.
CONSTITUTION: A roller manufactured of harder material than the aluminum alloy of a wheel is pressed to the surface of the aluminum alloy wheel in cold with the forced quantity in a range of 0.02-0.30mm to apply plastic working to the surface of at least the disc part of the aluminum alloy wheel, and then buffing is applied. The fatigue strength of the aluminum alloy wheel is thereby improved remarkably, and the durability can be enhanced. Buffing time at the time is shortened so as to save the processing cots.
