The effect of destabilization heat treatment on the microstructure, hardness, fracture toughness and abrasive wear resistance of high chromium hardfacing was investigated. The results from the study shows that the hardness, frac­ture toughness and abrasive wear resistance are influenced by temperature of destabilization heat treatment and air and furnace cooling conditions, respectively. Destabilization treatment of materials by furnace cooling caused higher secondary carbides in the dendritic austenite whilst by air cooling it showed smaller particles of secondary carbide. Also, it was found that destabilization temperature at 1,000°C improves hardness compared with hardfacing after weld depositing. The study, however, indicated that Palmqvist fracture toughness method is a useful technique for measuring the fracture toughness of high chromium hardfacing compared to Vicker’s hardness method.

WC-10Co-4Cr cermet coatings were deposited on Inconel 718 alloy using the HVOF technique, then were heat treated by isothermal treatment (500°C, 3hours). The influences of isothermal heat treatment on micro-hardness, fracture toughness and abrasive wear resistance of WC coating were studied in this paper. The results show that the micro-hardness and fracture toughness of WC coating decrease after isothermal heat treatment, then the metallic blinder breaks up and the tungsten carbide particles pull out during abrasive wear test. Finally, it was concluded that the abrasive wear resistance of WC-10Co-4Cr coating decreased after isothermal heat treatment (500°C, 3hours).

Hardening Heat Treatment

The application of hardening heat treatment process at high temperatures (1100-1170 °C) for high-chromium steels of martensitic-carbide class 95Kh18 and Kh12MFL has been studied. Metallic substrate consisted of high-carbon martensite and residual metastable austenite with some traces of carbide has been obtained. Experiments have shown the resulting structure gains high frictional hardening capacity upon the application of heat. Sufficient amount of cooling martensite can be traced in the analyzed steel after high-temperature quenching (cooling up to the temperature of-70°С). Being combined with residual metastable austenite, it provides the increase of abrasive wear resistance by 25% compared with high temperature annealing. The influence of tempering temperature on hardness and abrasive wear resistance of analyzed steels 95Kh18 and Kh12MFL has also been determined.

This paper presents the results of tribological tests performed on a T-11 pin-on-disc type, which made it possible to determine the intensity of abrasive wear of steel 20MnCr5 subjected to selected thermo-chemical heat treatments. The tested steel, after the hardening and tempering process, is characterized by high endurance parameters and is used on heavily loaded machine parts. It is frequently used for elements subjected to intense abrasion. The analysis involved the following: carburizing, boronizing, and various methods of diffusion chromizing. For large loads, it is advisable to apply boronizing or carburizing with hardening. Chrome plating entails a very thin layer of increased hardness, which is characterised by a low abrasive wear resistance at high loads.

This paper studies the influence of variables such as holding temperatures and times during austempering of High Chromium White Cast Iron (HCWCI), with the following chemical composition: Cr 25 %, C 3 %, Si 0.47 %, Mn 0.74 % and Mo 1.02 %. The aim of the austempering was to modify the percentage of retained austenite and its correlation to abrasive wear resistance under different conditions.Microhardness tests, SEM-EDS and XRD were performed to determine mechanical properties, chemical composition, and type of carbides and microstructures present, respectively. The tests complied with the ASTM G-65 standard. Results showed that the best performance against abrasion was achieved for austempering at 450 ºC with holding time of 6 hours.
