Thin Dense Chrome (TDC)

Thin Dense Chrome (TDC) is designed to enhance the durability, wear resistance, and overall performance of metal surfaces without significantly impacting dimensions. It involves depositing a thin, tightly adherent layer of chromium direct to the substrate. The resulting plating layer exhibits remarkable hardness, provides excellent corrosion protection, and has a low coefficient of friction.

TDC can achieve similar results as Hard Chrome with a thinner deposit thickness. Hard Chrome is usually thicker (0.001-0.020”) and needs to be ground to size, while TDC only needs a minimal thickness (0.0001-0.001”). The precise and uniform coating thickness achieved through TDC plating ensures that intricate geometries, threads, and critical dimensions of the original component are preserved.

Greystone has 91+ years of chrome plating experience, and is often able to plate high volumes with more consistent and uniform deposits.

Benefits of Thin Dense Chrome (TDC):

The key advantage of TDC plating is its ability to significantly increase the surface hardness of the coated component. This enhanced hardness, typically measuring between 65-70+ HRC, provides superior resistance against abrasive forces, minimizing wear and extending the component's lifespan. Additionally, the low coefficient of friction of the TDC coating contributes to reduced friction and smoother operation, making it an ideal choice for parts subjected to sliding, rotating, or contacting motion.

Thin Dense Chrome plating offers a remarkable combination of durability, aesthetics, and corrosion resistance, making it an ideal choice when compared to other surface coatings for a wide range of applications across various industries. Whether you're seeking enhanced performance, wear resistant plating or part longevity, Thin Dense Chrome plating stands out as a reliable and effective solution.
