Journal of Physics: Conference Series, 2020 Abstract The 18CrNiMo7-6 steel billet was prepared by the process of EBT→LF→VD→die casting and forging. The position distribution, composition, type and cause of inclusions in the billet were statistically analysed by ASPEX and scanning electron microscopy. The results show that there are obvious distribution differences of inclusions in

Effect of Normalized Cooling Rate on Structure and Hardness of Gear Steel 18CrNiMo7-6
Teshugang, 2013 Tested steel 18CrNiMo7-6 (/%: 0. 17C, 0. 59Mn, 0. 24Si, 1.56Ni, 1.71Cr, 0. 28Mo) is a case-hardening steel for gear, it is required that the structure of normalized steel is ferrite + pearlite and has lower HB hardness value.

Effect of the Carburizing Process on the Microstructure and Properties of 18CrNiMo7-6 Steel
High-temperature carburizing heat treatment of 18CrNiMo7-6 steel was carried out at 930 °C, 950 °C and 970 °C. The effects of carburizing process on the microstructure, hardness and wear resistance of 18CrNiMo7-6 steel were studied. The results showed that the microstructure after high-temperature carburizing was mainly tempered martensite, and there ...

The Effect of a Gear Oil on Abrasion, Scuffing, and Pitting of the DLC-Coated 18CrNiMo7-6 Steel [PDF]
Coatings, 2018 The transmissions of mining conveyors are exposed to very harsh conditions. These are primarily related to the contamination of the gear oil with hard particles coming from coal and lignite, which can cause intensive abrasive wear, scuffing, and even pitting, limiting the life of gears.
