SINTERED ARTICLES OF IRON POWDER, COATED BY ELECTROCHEMICAL CHROME PLATING MODIFIED WITH DIAMOND NANOPARTICLES

摘要

This patent application relates to a sintered iron-powdered product with increased mechanical and chemical properties consisting of a base comprising of sintered iron powder and coating material, characterized by the coating which is chromium, electrochemically deposited and modified with diamond nanoparticles measuring from 1 to 200 nm. The sintered articles have reduced surface porosity, increased corrosion resistance and increased wear resistance; Their micro-stability reaches values of 1047.0 to 1072 MPa. 1 claim, 2 figures
