Method of forming wear resistant surfaces on aluminium-silicon alloy workpieces

摘要

The invention relates to a method for the production of wear-resistant surfaces on components consisting of an Al-Si alloy, in which the surfaces are coated with a layer of a binder, pulverulent silicon, a nucleating agent for primary silicon crystals and a flux, and this coating is then melted by means of laser energy. A simple application method for the alloy elements is the screen printing technique.
