CK45 20MnV6 Chrome Steel Rod Metric Hydraulic Chrome Bar
Introduction of Chrome Steel Rod
The hardness test of chrome-plated rods should use different
hardness testers according to the size of the part, the base
material, the thickness of the coating, the diameter of the
indentation, and the size of the load. When measuring the hardness
of the coating, a Vickers micro-hardness tester is often used, and
a load of 5g to 200g can be added according to the thickness to
make the indentation depth reach 1/7 to 1/10 of the thickness of
the coating. When the thickened chrome plating layer is greater
than 100μm, it can be tested by Rockwell hardness tester.
The wear resistance is usually measured by the thickness reduction
method, mass loss method, volume wear method, grinding medium
consumption method, cutting thickness time method, radioisotope
method, etc. The test shows that the Vickers hardness of the
chromium layer in the chrome-plated rod is 7355MPa-7845MPa, which
has a relatively high wear resistance. The thickness of the chrome
plating layer also has a certain relationship with the wear
resistance and also has an impact on the service life.
