Abstract

PURPOSE: To form excellent protective coating, by painting a paste mixture made of chromium, titanium hydride, yttrium hydride using nickel-boron eutectic component as a medium, and by heating the painted coating.
CONSTITUTION: A mixture made by using Cr and powder of low-melting component Ni-B eutectic alloy having high diffusing power as a medium, and by adding Cr powder, TiH4 and/or YH4 powder, if necessary by addition with at least one of Co, Al, is made paste with an org. binder, and is painted on the surface of a porous corrosion-resistant protective layer to form, for example, a layer 0.1W0.2mm in thickness and is heated in an inert atmosphere at a temp 1,000W1,200°C for several minWten-odd hr. The mixing ratio is ≥30% Ni-B, <15% Cr, 5W10% TiH4 calculated as Ti, 0.01W1% YH4 calculated as Y, 10W30% Al. Hereby dense, corrosion-resistant protective layer excellent in adherence and peeling resistance is formed.
