The effect of different cryogenic treatments on the wear behavior of chromium base die steel under dry condition has been examined at five levels of sliding velocity and normal loads. Parameters chosen for cryogenic treatment cycles are subjected to soaking duration of 6, 21, and 36 h at soaking temperatures of −154 ℃ and −184 ℃. Soaking period of 21 h shows higher wear resistance, whereas 36 h treatment shows the reduction in wear resistance. Worn out surface and wear debris exhibit that mechanisms responsible for wear of samples are rupturing of martensitic matrix and delaminating.

Dry sliding tests were performed under various sliding speeds and loads in air for AISI H13 steel with different hardness values. Through investigating morphologies, compositions and phases of worn surfaces, the wear behaviors and mechanisms of AISI H13 steel as a function of sliding speed and hardness were explored, and especially, the effects of friction-oxide layers and their stability were disclosed. Sliding speed and the hardness of the steel significantly affected the wear behavior and mechanism due to the evolution of friction-oxide layers. With an increase of sliding speed, more oxides were produced by the process of friction oxidation. The stability of friction-oxide layers became a key factor in determining wear rate, which was closely related with the hardness of the steel. Those friction-oxide layers formed on the quenched and tempered steel with lower hardness remained stable, providing more protection from wear. Three types of wear mechanisms were found to prevail. Adhesive and abrasive wear were dominant accompanied with oxidation mild wear at relatively low sliding speeds, where the wear resistance was proportional to the hardness of the steel. As sliding speed increased, oxidation mild wear became dominating, where the wear resistance was not related to the hardness of the steel. As the sliding speed further increased, the wear fell in oxidation mild-to-severe wear transition region, in which the wear resistance was inversely proportional to the hardness of the steel.

In this study, AISI H13 steel was plasma nitrided in two different atmospheres, containing 25%N2-75%H2 and 4%N2-96%H2 at a constant temperature of 530oC and 6h-holding time. Dry wear behavior of nitrided samples was determined with pin-on-disc method at 25oC and 500oC, under 10N and 30N loads. The results indicated that the nitrided steels, which had a thin multiple phases white layer (produced at 4%N2-96%H2 atmosphere), didn’t have any wear resistance in ambient and elevated temperatures. However, the nitrided steels, having thick single phase white layer (produced at 25%N2-75%H2 atmosphere), showed better wear resistance in ambient temperature than in elevated temperature.

Steel Substrates

Cr coatings were deposited on AISI H13 steel substrates by means of electrospark deposition (ESD). The coatings were characterized in terms of their microstructure, hardness, friction and wear behavior and high-temperature oxidation resistance. Micro-indentation and tribometer testers were employed to measure the mechanical properties of Cr coatings and AISI H13 steel. The results showed that the hardness of the coatings ranged from 600 to 660 HV, with a higher value than that of AISI H13 steel (510 HV). The coefficient of steady-state friction of the coatings against 45-carbon-steel balls ranged from 0.23 to 0.27, with a lower value than that of AISI H13 steel (0.62-0.68). The isothermal oxidation behavior of the coatings at 850°Cwas studied in comparison with AISI H13 steel substrates. The results indicated that Cr coatings substantially increase the high-temperature oxidation resistance of AISI H13 steel and the oxidation process was retarded mainly by the presence of a Cr2O3 oxide scale on the coatings at 850°C for 100 hours.

Tempering Time

The mechanical properties, microstructures and precipitation behaviors in AISI (American Iron and Steel Institute) H13 steel tempered at 863 K for 0.5, 2, 4, 10 and 20 h were investigated. The values for H13 tempered for 2–4 h resulted in die steel that reached the desired properties as specified in NADCA (North American Die Casting Association) #207-2016. The cubic Ostwald ripening model was applied to simulate the coarsening of the large carbides, which were mainly M23C6 and M3C, as determined from FactSage predictions as well as measurements with transmission electron microscopy (TEM). TEM revealed that the equivalent circle radius (ECR) decreased during 0.5–2 h, because of the nucleation of many new precipitates. According to the Ashby-Orowan modified precipitation strengthening model, this decrease in ECR leads to an increase in the contribution of precipitates to yield strength. Between 2 and 4 h tempering, the ECR of large carbides increases sharply but then increases asymptotically from 4 to 20 h, which obeys the calculated Ostwald ripening rate for cementite and M23C6 in H13 after 863 K tempering. This observation for the Ostwald ripening of M23C6 is in agreement with experimental data for other steels in the literature.
