Q. I have a hard chrome plating problem. Pits are found on a half inch dia. rod (tool steel) after the plating process. The density of the pitting holes is about 1 in every mm. They are not uniformly distributed around the rod. The pitting is about 200 micron in diameter at the ...
Electroplated hard chrome coating is widely used as a wear resistant coating to prolong the life of mechanical components. However, the electroplating process generates hexavalent chromium ion which is known carcinogen. Hence, there is a major effort throughout the electroplating industry to replace har...
the parameters selection also impacts the surface roughness but their effects are broadly interactive and complex in nature thereby arising the need of optimization for an adequate process control. In general, larger diameters coupled with medium steps result into good finish; very small steps are lik...
Fig. 2b. The cuboid specimens were then heat treated after the rouging process, which is also recommended in the processing instructions of the material producer before finishing machining. The PWHT was performed in the following steps, as also recommended by the material producer: Solution ...
The present invention pertains to a process for producing an article from a layered hard coat object including a hard coat layer and a transparent-resin film layer in this order fro
[0024] In another embodiment of the present invention, a process for making a circuit assembly includes the steps of forming a plurality of traces directly on a first surface of a base member, wherein the traces extend between a first end and a second end of the base member; forming a ...
The method comprises the following steps: checking the appearance quality of a to-be-plated workpiece; removing oil, namely removing grease dirt on the workpiece completely by adopting acetone and lime water; and mounting a special clamp for radial eyelet chrome plating for the mandrel, cleaning ...
