Annotation

This specification covers the requirements for aluminum diffusion of metals applied by pack cementation process. The three classes of aluminum diffusion coating, defined by the type of base metal, are as follows: Class I (carbon and low alloy steels); Class II (stainless steels); and Class III (nickel-based alloys). Specimens shall adhere to processing requirements such as substrate preparation, high and low activity pack mix, materials (masteralloys, activators, and inert fillers), loading, furnace cycle, post cleaning, diffusion heat treatment, post straightening, visual inspection, and marking and packaging. Specimens shall also adhere to coating requirements such as diffusion thickness, aluminum content, appearance, and mechanical properties (tensile strength, and macro- and micro-hardness).
