Gears - Surface Temper Etch Inspection After Grinding

Organization: ISO
Publication Date: 15 December 1995
Status: inactive
Page Count: 11
ICS Code (Gears): 21.200
scope:

This International Standard specifies standard procedures and requirements for the detection and classification of localized overheating on ground surfaces by chemical etch methods.

Some methods which have been used in the past are no longer recommended. Specifications should be changed to use the methods in this International Standard. These etching methods are more sensitive to changes in surface hardness than most hardness testing methods.

This International Standard applies to steel parts such as gears, shafts, splines and bearings, but is not applicable to nitrided parts and stainless steels.

NOTE 1 This process, although at times called "nital etch", should not be confused with other processes also known as "nitai etch".

The surface temper etch procedure is to be performed after grinding and before additional finishing operations.
