摘要
A method of standardizing a grinder burn etch test may include machining a test sample of substantially equivalent chemical composition and heat treatment to a manufactured part to be audited for grinder burn and receiving data on an expected range of thermal damage that may be caused on the manufactured part during grinding by grinder burn. The method may also include preparing the test sample by laser heat treating at least a portion of the test sample to create a range of thermal damage across predetermined areas on the test sample, wherein the range of thermal damage on the test sample encompasses the expected range of thermal damage that may be caused on the manufactured part during grinding by grinder burn. The method may still further include testing a grinder burn etch bath with the test sample to determine whether the etch bath can detect thermal damage across at least a threshold percentage of the expected range of thermal damage that may be caused on the manufactured part.
