From the study, the following conclusions were drawn:
1) Cow bone can be used as energizer supply of atomic carbon.
2) The carburizing compound with 90% charcoal / 10% cow bone gave the highest average case depth of 2.32 mm and therefore it gives better results than the other three compounds.
3) The average case depth was increasing as the cow bone in carburizing mixture was increased.
4) 4-carbonates of calcium as energizer at 10% for above media for pack carburizing and show small influence on obtaining result for cow bone
