Abstract
In a method of making a load-bearing article by spray casting a molten metal onto a metal substrate, the substrate surface receiving the spray cast deposit is treated by vacuum cleaning, boronizing and/or knurling to enhance the structural integrity of the diffusion bond joint subsequently formed between the spray cast deposit and the substrate in sustaining a load across the joint without premature joint failure.
