Date Run:
12/13/2023
Experiment Procedure:
Three pre weighed stainless steel parts were used as coupons. The coupons were soiled by swabbing the bottom third of the coupons with water Strawmann Cutting Oil. The dirty weights of the coupons were then recorded. The coupons were then subjected to a one-minute heated cycle at 140 degrees F in the VCN using water, LF 2100 1%, and Alcojet 1%. The coupons were then removed and left to air dry overnight. The next day the clean weights of the coupons were recorded.
