Abstract:

Several methods of casting babbitt metal to steel were evaluated for bond strength by use of tensile-type specimens. The methods investigated were the use of a tin bath, torchtin stick, and electroplated nickel to insure proper babbitt-to-steel bond, as well as no tinning. Of the methods performed, only the tin-bath method consistently produced a bond stronger than the babbitt metal itself. The bond strengths developed in the other methods tested were erratic and always less than that obtained with the tin-bath method. The torch tin stick method gave an adequate compromise between bond strength and convenient application. It was found that the oxide formed on the tinned surface which precludes good bonding could be effectively removed by the use of flux during babbitt casting. Author
