When they return to our plant, we centerless again then plunge grind this diameter. This grinding operation actually goes thru the plated diameter at either end and also thru the diameter in the form of a groove near the middle of the part. We then centerless grind again to establish finish size.

The causes of and remedies for defects in hard chromium deposits are explored in the first of this two-part P&SF article from 1984. Photomicrographs and SEM (scanning electron microscope) photo­graphs will illustrate that most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original …

This phenomenon is attributed to the fact that grinding of steel often causes a surface flow of the material, which is eliminated during the preplating treatments, making the crack apparent as the coating thickness increases. The deposited …

HARDCHROME PLATING For information please contact: THE PROCESS Hard Chrome plating is an electrolytic method of depositing Chrome for engineering applications, from a Chromic acid solution.

It is the nature of the beast with hard chrome plating. The plating process is very low efficiency, you have to put a lot in to get a little out. The extremities are what we call high current density areas and consequently you get uneven growth of plating over the part. When you call up the higher thicknesses the extremities will form these ...

Ra Surface Finish and Roughness Average November 3, 2016 by NSC Industry Resources news-press-releases Ra Surface Finish (Roughness Average) When measuring how smooth a turned, ground & polished (TGP), chrome plated hydraulic cylinder rod, or any other cold finished bar, the primary reading or parameter used is Ra surface finish.

It is the tiny area under the grinding wheel where the chrome reaches a high temperature and then immediately cools off as soon as the wheel moves. Causes: The grinders are taking too deep a cut per pass They are using the …

Now for the 5 most common problems and how to fix them: 1. The workpiece is burnt. In the feed too fast - Reduce the amount of stock removed per pass. Dressing on the wheel is too fine - Use a coarser dressing, more 'open'. Poor coolant direction - Adjust the coolant direction into the grinding area. 2.

TUFFTRIDE® process is used as an alternative to other surface engineering processes such as case hardening, galvanic (e.g. hard chrome plating), and other coating processes (plastic coating, painting, laser coating etc.), also plasma or gas nitrocarburizing with equally good or improved quality and greater economy. Carrying out the process

Industrial chromium plating, also known as hard chrome or engineered chrome, is used to provide a working surface that requires one or more of the following characteristics: to reduce friction, add wear resistance, or increase corrosion resistance, as well as, chemical inertness, wetting or galling. It is very hard, measuring between 66 to 70 HRC.

The different kinds of metal finishing. "Though there may be some confusion regarding metal finishing, it is a critical part of metal product production. Metal finishing includes an array of processes such as metal plating, chemical finishing, electroplating, buffing, grinding, sand blasting, and on.

Verbrugge, a company specialising in industrial chrome plating since 1941, guarantees the excellence of the process.. Performing a surface treatment by hard chrome plating lets you choose the thickness of the deposit, the material of your part, its hardness on the surface, its final roughness…. This electrolytic treatment allows to reduce considerably the friction coefficient.

When the object becomes heated enough, the gases expand toward its surface and push against the chrome plating, creating a visible bubble or blister. A severe blister can also cause the plating to lift off entirely. Blistering can also occur if the object's surface was unclean when the plating occurred.

This behavior can be attributed to the combined effect of better adsorption/reaction of the additives to the chromium surface providing protection against galling, the smoothening of aggressive roughness features from the grinding process by gentler features due to the chrome plating, and low adhesion of the strip material to the chromium layer.

Further inspection. During the hard chrome plating process, stanchions are regularly inspected and measured to ensure that the plating is to the correct thickness before finishing. Numerous measurements are taken to ensure that there's a constant diameter throughout the …
