Metallographic Study

In this work, ultrahigh carbon steels (UHCS) obtained by powder metallurgy with CIP and argon sintered at 1150°C. Then, they were rolled at 850 °C with a reduction of 40 %. Finally, steels were quenched at 850 and 1000 °C in oil. In each step, hardness, bending strength and wear performance were evaluated. Obtained results are justified with a metallographic study by SEM. Both mechanical properties and wear resistance are highly favoured with the thermomechanical treatment that removes the porosity of the material. Moreover, final quenching highly hardens the material. The obtained material could be used as matrix for tool steels.

In order to improve the surface property of the steel tire mold, carbon steels were processed by electroless Ni-P and Ni-P-PTFE under contrast experiment. The coatings were characterized by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometer (EDS). The wear resistance and corrosion resistance of the coatings were explored by tribometer, salt spray cabinet and advanced electrochemical system. The experimental results showed that the Ni-P coating was amorphous structure, and the Ni-P-PTFE coating was micro-pore structure; The wear resistance of Ni-P-PTFE coating was superior to Ni-P coating; In view of the micro-pore structure, the corrosion resistance of Ni-P-PTFE coating was worse than Ni-P coating, but they were all superior to carbon steels, and the service life of the steel tire mold were improved.

Oxygen Fuel

Tube boiler operating condition initiates common problems that can occur as a problem in the wear resistance material. It leads to a decreased function of the material so that it is necessary to repair or replacement. High Velocity Oxygen Fuel (HVOF) is regarded as one of the effective methods to increase the wear resistance of the material. In this study, the materials were ASTM SA213-T91 as a material commonly used for boiler tube and JIS G 3132 SPHT-2 as an alternative material. In the early stages, both of specimens were given initial surface heating with temperature variations 0, 50, 100 and 150oC. The materials were then coated with Stellite-1 using HVOF method. The material were then characterized for the microstructure, porosity, hardness distribution, and wear resistant. The results showed that the coating Stellite-1 as a top coat with HVOF method can improve the performance of the material. Microhardness increases from 220 HV to 770 HV on ASTM SA213-T91, while on the substrate JIS G 3132 SPHT-2 the microhardness increased from 120 HV to 750 HV. Better wear resistance was achieved with increasing preheating [1]. Wear resistance of the materials increased from the range 3.69x10-7at 0°C preheating up to 0.89x10-7on a specimen with initial surface heating 150oC. Porosity also decreases with the increasing preheating temperature.

Martensite Structure

Nitriding of carbon steels does not allow for adequate hardening of the substrate of layers and core required in some applications. Such hardening can be achieved by using further heat treatment. As a result of this heat treatment, the zone of nitrides vanishes and a nitro-carbon martensite structure is formed, additionally hardened by ageing. The carried out tribological tests have shown that subjecting nitrided carbon steel to further hardening treatment significantly improves its wear resistance in comparison to nitrided steel, and the zone of good wear resistance goes deeper.

Comprehensive Overview

A comprehensive overview of the structural factors on which the hardness of steel depends is presented, as well as methods of increasing the hardness and wear resistance of inexpensive, economically alloyed high-carbon steels suitable for operation in abrasive wear and high contact stresses are discussed. The mechanism of increasing the hardness of the material by multiple (cyclic) cold treatment of high-carbon steels hardened on martensite is considered. It is shown that quadruple cold treatment (with cooling to –70 °С) of rolls from cheap low-alloy steel 170Х2Ф increased their hardness from 58 – 59 HRC to 67 – 68 HRC, exceeding the indicators of the best foreign analogues. The possibilities of application of quenching with fast electric heating are described. It has been found that quenching of steel products with fast electric heating with high frequency currents (HFC), industrial frequency currents (IFC), passing electric current allows to increase their hardness on 2 – 4 units of HRC compared to quenching with relatively slow furnace heating. At the same time, the more dispersed the initial structure of ferrite-cementite mixture, the smaller the cementite plates in it, the greater the value of hardness increase during quenching with rapid electric heating. The effect of ultra-low tempering on the hardness of steel has been investigated, and it has been shown that in order to achieve high hardness of the material, it is desirable to use ultra-low tempering of high-carbon martensite at 100 – 140 °С, which contributes to the creation of nanoneodenicity on carbon, and allows to further increase hardness of low-alloy high-carbon steels by 1.5 – 2.0 units of HRC.
