Corrosion Rate Evaluation Procedure (CREP): A Convenient Reliable Method for Determining Corrosion Inhibition Ability of Lubricants (Preprint)

Abstract

The Corrosion Rate Evaluation Procedure (CREP) was first designed as a screening test for corrosion inhibited aerospace gas turbine engine oils as a substitute for the Humidity Cabinet corrosion Test (ASTM D1748) in order to screen large numbers of oils in a short period of time for their ability to prevent rust. The CREP was later adapted for hydraulic fluids and greases because of its simplicity, low cost, and speed. For greases it is an alternate method to ASTM D1743 and can evaluate corrosion protection in 1.5 to 2 hours using only 2-4 milligrams of grease. The metal coupons, used in the CREP test, are low cost and available in a variety of metallurgies. The CREP is convenient, reliable, adaptable, cost effective, and usable with greases, liquid lubricants, or hydraulic fluids and various metals as desired.
