根据GB304.1-81自润滑关节轴承滑动表而应镀硬铬.由于关节轴承的内圈滑动表面是一个球面,用轴承内外配合镀硬铬工艺难以使整个球面铬层均匀. 为了使球面铬层均匀,如果根据电镀原理和电力线分布,设计一种专用阳极,其表面为球面,使阳极球面上各点与阴极球面上各点的距离相等,电力线分布均匀,球面镀层就能均匀.为此要确定阳极球面的曲率中心位置和曲率半径R的数值.如果阴极是一个完整的球面,
According to GB304.1-81 self-lubricating joint bearing sliding table and should be hard chrome plated .Because the joint bearing inner ring sliding surface is a spherical, with hard chromium plating process with the bearing inside and outside hard to make the entire spherical chromium layer .In order to spherical chromium According to the principle of electroplating and the distribution of power lines, a special anode is designed, whose surface is spherical, so that the distance between each point on the anode spherical surface and each point on the cathode spherical surface is equal and the power lines are evenly distributed and the spherical surface coating can be uniform. To determine the center of curvature of the anode sphere and the radius of curvature R. If the cathode is a complete sphere,
