| titleOfInvention | PROCESS FOR MAKING AN IRON ELEMENT |
| abstract | A method (100) of manufacturing a ferrous member (118, 212) having a friction surface (216), the method (100) comprising: rotating (106) a first portion of the friction surface (216) at a sufficient feed rate and cutting depth (125) to create a first deformed layer on the first portion of the friction surface (216), the first deformed layer being a nanocrystallized microstructure layer (128 ) includes; polishing (108) the first portion of the friction surface (216) to achieve a predetermined first roughness (Ra); nitrocarburizing (110) the iron element (118, 212) for a time and temperature sufficient for nitrogen atoms and carbon atoms to diffuse through the nanocrystallized microstructure layers (128), Finish turning (106) a second portion of the friction surface (216) at a feed rate sufficient to create a second deformed layer on the second portion of the friction surface (216), the second deformed layer comprising a nanocrystallized microstructure layer (128) that is thinner as the nanocrystallized microstructure layer (128) of the first portion of the friction surface (216); and polishing (108) the second portion of the friction surface (216) to achieve a predetermined second roughness (Ra); wherein rotating (106) the first portion of the friction surface (216) includes rotating (106) the ferrous element (118) about an axis of rotation at a speed of 400 to 1000 revolutions per minute (RPM) and removing a layer of material from the surface of the first portioning the friction surface (216) with a cutting tool (121) having a feed rate of 0.25 to 1.00 mm per revolution and a cutting depth (125) of 0.2 to 0.8 mm; and wherein polishing (108) the first portion and the second portion of the friction surface (216) includes applying a polishing pressure of from 5 megapascals (MPa) to 25 MPa. |
