One kind of Finish in CNC Machining: Black Oxide
Black oxide is a type of conversion coating for ferrous materials, such as steel and stainless steel, which blackens the top layer of the material. This post-processing method is widely used in automotive, aerospace, and medical devices. 1. Enhanced corrosion resistance. In industries such as automotive, aerospace, and medical devices, corrosion resistance is crucial, such as, computer radiators in the picture. Black oxide provides a layer that helps prevent rust and corrosion. 2.Improved aesthetic appeal with a sleek, black finish. The finish also tends to highlight the intricate details of CNC machining, giving the final product an elevated appearance. 3.Increased wear resistance. CNC-machined parts often undergo heavy usage, and black oxide can improve the surface hardness of components, reducing the risk of scratching or wear. 4.Minimal dimensional impact on the part. Unlike thicker coatings, which can add to the overall dimensions of the part, black oxide adds only a thin layer to the surface, ensuring that the part remains within tight tolerances after finishing. This is crucial in precision CNC machining, where even a small deviation can affect the overall performance of the part. https://www.szinfosion.com
