Plasma electropolishing of components made of copper, steel, and alloys of zinc, nickel, chromium, and other metals using a single-component electrolytic solution<\/h1>\n

This improvement in surface roughness is achieved through this new plasma electropolishing (PEP) process.[\/vc_column_text][vc_empty_space][vc_single_image image=”5036″ img_size=”full” qode_css_animation=””][vc_empty_space][vc_column_text]<\/p>\n

How does it work?<\/span><\/h3>\n

[\/vc_column_text][vc_empty_space][vc_column_text]The electrolytic solution used in this technology consists primarily of ammonium sulfamate. It is a single-component solution, free of the unpleasant odors typical of moderators, and is potentially environmentally friendly and non-toxic. It is also reusable, as it converts the metal layers into a basic compound without altering the initial composition. <\/p>\n

The solution acts on two main groups of metals: copper alloys (and pure copper) and steel alloys (e.g., 316L, 17-4PH, and similar). The polishing effect on steel is more uniform compared to the electrolytes described in the literature, preventing areas of corrosion. It is less sensitive to variations in composition and purity typical of 3D printing, ensuring greater reliability on particularly rough surfaces.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n
