Evaluation of Titanium Diboride Gun Tube Coatings

Abstract

Samples of AISI 4140 and AISI 4130 steel were coated with the intermetallic compound titanium diboride (TiB2) by means of a relatively low temperature electrodeposition process which does not harm the steel substrate. The erosion resistance of these samples was evaluated at various pressure levels in the U.S. Army Armament Munitions and Chemical Command vented closed bomb test fixture using laboratory prepared M30 propelling charges. The coasted samples apparently eroded faster than steel. The effects of the TiB2-steel interface dominated the data to such an extent that no legitimate comparison between steel and TiB2 could be made.
