TiN, TiAlN, CrAlN and TiAlN/TiSiN films were deposited on AISI H13 hot work steel substrate by cathodic arc evaporation method. Each coating was optimized in laboratory conditions and the highest hardness and wear resistance coatings were taken into consideration for this study. Morphological properties, chemical compositions, crystallographic structure, nano hardness and adhesion strength of coatings were analyzed with SEM, AFM, EDS, XRD, nano indentation and scratch resistance tester. Wear experiments were performed using ball-on-disk tribometer against Al2O3 ball of 6[Formula: see text]mm diameter and wear volume of coatings were measured using optical profilometer. Wear experimental results revealed that all coated samples showed higher wear resistance and hardness than uncoated AISI H13 steel substrate. The highest wear and scratch resistances as well as nano hardness were attained for CrAlN coating. TiAlN coating has the lowest scratch resistance and wear resistance. Adhesive wear mechanism was the dominant wear mechanism for CrAlN coatings which is the highest wear resistant coating. Abrasive wear mechanism was the dominant wear mechanism for TiAlN coatings which is the lowest wear resistant coating.

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.

A resin matrix compound coating is prepared by taking epoxy as the matrix and α-Al2O3 particle as the reinforced phase. By simulating the actual wear conditions of pipes in the heavy medium coal preparation in a laboratory, the paper explored the change law of the erosion wear resistance of wear-resistant coating with different reinforced particle sizes and abrasion angles, and discussed the wear mechanism by combining with abrasive appearances. The results show that reinforced particles with a lager particle size (60 mesh) are of excellent erosion wear resistance when the erosion wear particle is smaller (200 mesh), and the α-Al2O3 particle wear-resistant epoxy coating with a particle size of 60-80 mesh is of good erosion wear resistance under the condition of heavy medium coal preparation and is suitable to be a wear-resistant coating material.

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.

Rotary Cutting

Wearing of conical picks on a coal mining machine and roadheaders are investigated experimentally using a full-scale rotary cutting machine. This study considers three types of conical picks with different tip materials to examine the effects of wear resistance of conical picks and wear characteristics in response to cutting load. The influence of pick wear on the cutting load and pick tip temperature are analyzed, thereby providing an experimental-based guideline for reducing pick wear. The results indicate that the cemented carbide pick has the best wear resistance among the three kinds of picks studied, and the pick life can be significantly extended for picks with a wear-resistant coating surface. It is also found that pick wear has the greatest influence on the normal force. Thermal fatigue and overloading are two factors that cause pick wear failure. The results can also be used to design the conical pick with wear-resistant coating and to validate the numerical models.
