Claims7
A method for heat treating and aluminizing compactly shaped ferrous alloy products comprising the steps of pre-heating said products to a temperature of 100.degree. to 400.degree. C., immersing the pre-heated products in a molten metal bath of liquid aluminum or an alloy of aluminum at a temperature of 550.degree. to 950.degree. C. for 15 seconds to 30 minutes at a controlled speed rate between 0.1 to 12 m/min, removing the products from said bath at a controlled speed rate between 0.1 to 12 m/min, and cooling the products in air or water.
