Along with the increase of the current density, cathode polarization effect, coating grain with increasing more and fine.
随着电流密度的增加﹐阴极极化作用随着增加﹐镀层晶粒越来越细。

Because the cathode polarization effect more than a range, will lead to a large number of hydrogen, and separation coating becomes porous, rough, loose, scorched, even the powder, quality just drop.
The carbon fiber is the main reinforcer for titanium diboride coating material, and greatly influence the properties of titanium diboride coatingcathode.
