Effects of Ion Implantation on Electroplated Chromium.

Abstract

In this report, the effects of ion implantation on two kinds of electroplated chromium have been studied. Both hard chromium and low contraction chromium were plated onto samples of 4340 grade steel and subsequently implanted with N2(+) or Ar(+) at atom energies of 75 keV. The dose was varied from 9.4 x 10(exp 15) to 3.1 x 10(exp 18) atoms/sq cm and the implantations were conducted at both room temperature and 500 deg C. SIMS and AES analyses, Knoop microhardness, and pin-on-disk wear testing were used to study the effects of ion implantation on the surface properties of the chromium plating. jg p11
