The use of chrome-plated piston rod performance analysis
May 09, 2018

In practical applications, there are certain requirements regarding the thickness and hardness of the chrome plating layer of the hydraulic piston rod. Under normal circumstances, the hard chromium plating of the chrome plated piston rod should be kept bright and delicate, and it should be firmly bonded to the substrate. The hardness of the chrome plated piston rod can be as high as HV1100.


In short, the chrome-plated piston rod coating should ensure smooth, uniform thickness, but also should have a strong dispersion. In the process of chrome plating, the entire process flow is relatively simple and stable. The operation and maintenance are relatively simple and can be directly converted. Furthermore, it contains no fluoride and does not corrode the workpiece substrate in the cathode low current density area. The number of micro-cracks in the hard chromium electroplating layer is more than 2000/cm, which can ensure strong corrosion resistance.


Not only that, after the chrome-plated piston rod is treated with hard chrome plating, it can improve the quality of the surface of the product, making it smooth and bright, and also has the functions of corrosion resistance, high temperature resistance, abrasion resistance, and rust prevention. For users, when using such a piston rod, it is not easy to damage, break, and dechromize under normal maintenance and use, thereby prolonging the service life, improving the quality, reducing the material cost, and improving the production efficiency.


From the above description, it can be seen that with a good chrome plating process, the obtained chrome-plated piston rod not only has better performance, but also has a longer service life. In fact, hard chromium plating ensures that the surface hardness and brightness of the product are improved, and the rust resistance, corrosion resistance, and wear resistance of the product are greatly improved.


In general, the optimal chrome plating thickness of the chrome plated piston rod is approximately 1 to 3 filaments on one side and a hardness range of approximately 750-890 HV. In this range, the hardness of the chrome piston rod can be moderated and the wear resistance is good. performance.http://www.xhychromerod.com/
