The effects of small metal additions on the wetting and adherence of aluminum to graphite were investigated. Sessile-drop tests were conducted to determine the contact angle. The apparent adherence of aluminum to graphite was determined by a tensile test of the special shape of specimens. In order to investigate the effects of small metal additions, various metals which belonged to the first long period in the periodic table were vapour deposited on the surfaces of graphite discs for the sessible-drop test and specimens for tenile test. Elements in Groups I, II and III of the periodic table increased the aluminum to graphite contact angle relative to that for pure aluminum, elements in Groups IV, V and VI had little effect, and elements in Groups VII and VIII increased the contact angle. On the other hand, elements in Groups VI, VII and VIII increased the apparent adherence of aluminum to graphite.
