Laser Treatment of Chromium Plated Steel

Abstract

Both flat steel coupons and rolls for a geared-roller test machine were chromium plated and laser treated in an effort to improve adhesion. Under the experimental conditions the electroplate was rendered considerably softer but more fragile. A Cr-Fe alloy was produced at the interface at the slower processing speeds and the steel under the electroplate was considerably hardened by the formation of untempered martensite. While this work shows only much decreased durability for laser-treated chrome plate, perhaps other experimental conditions might show improved properties.
