Abstract

PURPOSE:To simply form an anticorrosive hard layer preventing the corrosion of a Ti member by a sacrificial anode effect by spraying hot air on the surface of the member to locally form a thin hard layer and filling the pores of the hard layer with a specified deposited metal. CONSTITUTION:A flameless torch 1 with a heater built-in is applied to a prescribed surface part of a member made of Ti or Ti alloy such as a runner, and by spraying air heated through the torch 1, a hardened layer 2 made of titanium oxide is formed. An aqueous soln. of copper sulfate or the like for plating is impregnated into the part forming the hard layer 2, and a cloth pack 4 having an inserted platinum electrode 3 is placed. In this state a voltage is applied between the electrode 3 and the member and held for a prescribed time to fill the pores 2a of the layer 2 with deposited copper 5 or the like which is electrochemically baser than Ti. Thus, an anticorrosive hard layer 6 is formed. The layer 6 has superior wear and friction resistances.
