microstructure and microhardness distribution of the precision bearing race surface layer have been analysed and measured by modern surface physics methods
such as metallography
microhardness
X-ray diffraction
TEM
AES and XPS. According to the experimental results
a model of soften surface layer in bearing race has been suggested. Furthermore
application of ion implantation to strengthening surface of precision bearing race has been studied. The experimental results on GCr15 steel by N
