<p>A sheet metal substrate (44) is provided with a raised border (52) which surrounds an area to be coated with a hardfacing. A slurry comprising a highly alloyed powder and a PVA binder is placed in the cavity (54) defined by the border (52) and the steel plate (44). The border (52) has a height which exceeds the desired thickness of the finished coating, which is in excess of 2.0 mm by an amount equal to the shrinkage expected during curing and fusing steps.</p> |
