Nickel based alloys containing chromium, molybdenum, tungsten and other elements are commonly used for equipment production in the petrochemical, chemical process and power plants due to their supreme corrosion resistance in the oxidizing and reducing conditions. The availability of sufficient chromium content enhances the development of passive barrier oxide layer of Cr2O3 on the surface … Continue reading How nickel based alloys perform against localized corrosion

Acid solutions are widely used in chemical industry to eliminate mill scales from metallic surface. The inclusion of inhibitors suitable secures the metal against an acid corrosion. Usually acid inhibitors are organic compounds comprising of nitrogen, oxygen and sulfur. These compounds are adsorbed on the metallic surface blocking the active corrosion sites. Due to toxicity … Continue reading Corrosion behaviour of nickel and its alloys in HCl and its prevention by natural rosemary oil

Nickel-Chromium-Molybdneum alloys were selected as suitable materials for nuclear waste containers as they provide outstanding resistance to localized corrosion in conditions that may occur at the permanent repository site. It was crucial to determine if prolong exposure to low temperatures would be harmful to the resistance property of Hastelloy C22 , C4 and C276 alloys … Continue reading Which alloy is the best fit for nuclear waste containers

The fracture hardness of Inconel alloy 625 in the cast and welded conditions has been evaluated as a part of complete properties of alloy for advanced steam turbine applications. The fracture properties of solution treated alloy vary because of prolong aging at 650oC, with metallurgical precipitation causing changes to critical toughness and fracture resistance profiles. … Continue reading Evaluation of Fracture toughness properties of Inconel grade 625

With the variety of different thermal spraying processes, a wide range of gases is used majorly in applications for fuel gases and oxygen. Different hydrocarbons, particularly acetylene and hydrogen are used. Besides the fuel characteristics, aspects of the gas supply system are also crucial. Flame spraying guns can commonly be used for different fuel gases … Continue reading How Arc spray coating improves the function of application components
