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.

Chromium Cast Iron

The effects and the mechanisms of namo TiN on the high chromium cast iron are studied, the material has been prepared through infiltration casting and addition of high carbon ferrochrome powder and nano TiN powder. The alloy is formed on the surfaced of guide plate, and the wear resistance of alloy have been studied by means of SEM, XRD micro-analysis and wear-resistant performance. The grain size and the type of carbide in the organization are affected by nano TiN, and the wear resistance of carbon chromium alloy layer is affected by the type of carbide; when the addition of nano TiN is 1% (wt), the grain size is apparently refined, overeutectic primary M7C3 in the hypereutectic is precipitated uniformly in considerable amounts, therefore the wear resistance of alloy can be improved effectively.

Chromium Cast Iron

The wear behaviours of alumina strengthen 3Y-TZP ceramics worn against high chromium cast iron under various testing conditions were investigated using a block-on-block tribometer. The results showed that the wear rate increases with the increasing of the load and the sliding time. Under the low load the main mechanism governing the wear properties of ceramic is the apparent plastic deformation and ploughing, and the wear rate rapidly increases and the wear mechanism changes into brittle fracture under high load. Meanwhile the wear resistance is depended on the properties of the abrasive particle. As expected, the wear resistance was increased with decreasing hardness of abrasive particle, but it was also influenced by the morphology, that is, the sharper the abrasive particle the higher wear rate.
