Progress Report Ⅱ Use of Chaplets in Steel Castings

摘要

The influence of chaplets on the soundness and integrity of steel castings is studied using specimens prepared under carefully controlled laboratory conditions. Two sizes of bare, uncoated chaplets in each of three different styles were obtained from the same commercial firm which supplied the material of the initial work presented in Navy Report N-1561. Using different techniques both before and after coating the following surfaces were applied and tested: silver, silver-cadmium, cadmium, copper, and nickel plated; tin and aluminum dipped, colorized, and aluminum sprayed.
