Progress Report 2 on Use of Chaplots in Steel Castings
Abstract
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 H-156la 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, calorized, and aluminum sprayed. The influence of the various coatings was determined under varying conditions of preparation and storage. l/4n and 3/1.6 11 stem diameter types were tested under identical conditions to determine their relative tendencies to fuse satisfactorily. A well dioxidized steel was used in testing a series of badly corroded specimens to determine if the condition of the steel might not be a contributing factor to poor chaplet reaction.
