the aim of the present study was to investigate the effect of quenching and tempering temperatures on themicrostructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistantsteel. in addition, the dominant wear mechanisms were studied. for this purpose, austenitizing and temperingtemperatures were selected in the ranges of 900- 1000 °c and 300- 500 °c...

This paper was aimed to address the modeling and optimization of factors affecting the corrosive wear of low alloy and high carbon chromium steel balls. Response surface methodology, central composite design (CCD) was employed to assess the main and interactive effects of the parameters and also to model and minimize the corrosive wear of the steels. The second-order polynomial regression model...

The wear failure mode of a paver spiral blade was simulated by EDEM software. High-manganese steel, medium chromium alloy and high steel were selected as matrix materials; SiC particles WC surface particle reinforcement the prepared EPC process. performance mechanism analyzed microstructure, hardness, impact, pin disk, erosion test, morphology. Modeling with software applying discrete element a...

In most of the engineering applications, such as mining, metallurgy, agriculture; equipments are failed by the abrasive wear. The data as obtained form ministry of Research and Technology indicates that the percentage cost of abrasive wear in federal republic of German in metallurgy industry is 40%, mining industry 30%, agriculture 20% and production engineering 10%, and so the material selecti...

Chromium oxide coatings were deposited on low-carbon steel by radiofrequency reactive magnetron sputtering at different oxygen flux values. X-ray diffraction, x-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy were used to investigate the microstructure of chromium oxide coatings. Varying oxygen flux changed the coating microstructure; as with increasing oxyg...

-AISI D3 tool steel is a high-carbon, highchromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Typical applications for D3 tool steel include Blanking, stamping, and col...
