Gears - Surface temper etch inspection after grinding, chemical method
ISO 14104:2014 specifies procedures and requirements for the detection and classification of localized overheating on ground surfaces by chemical etch methods.
The process described in ISO 14104:2014 is typically used on ground surfaces; however, it is also useful for the detection of surface anomalies resultING from post-heat treatment machining such as hard turning, milling, and edge breaking (deburring) processes. Surface metallurgical anomalies caused by carburization or decarburization are also readily detectable with this process.
