Hardening Heat Treatment

Nickel-boron coatings were synthesized on mild steel by the electroless deposition method. Some of the coatings were submitted to a hardening heat treatment at 400°C during 1 hour in an atmosphere containing 95% Ar and 5% H2. Uncoated steel, treated and untreated samples were submitted to the Taber abrasion test to assess their wear resistance. The wear track was then examined by SEM and roughness measurement. The Taber Wear Index of untreated samples was slightly better than that of steel but heat treated samples attained TWI as small as 13. The corrosion resistance of the samples was investigated by the way of polarization and electrochemical impedance spectroscopy (EIS) and the influence of the heat treatment was observed.

Abstract The purpose of this paper is to review the early development of electro-carburisation technology and the research findings related to the electro-carburisation process. In general, conventional liquid carburisation of steel using a molten cyanide bath is carried out to improve the performance of mild steel, however this process produces toxic cyanide waste. Thus, other alternatives for liquid carburisation are necessary. Electro-carburisation process using carbonate-base molten salt, under a CO2 environment was developed as one of the alternatives to liquid carburising. Metal to be treated is exposed to the carbon-rich liquid in the molten cyanide bath and electro-carburisation. However, the metal is simply immersed inside the cyanide bath during conventional liquid carburising, while connected to the cathode in the electro-carburisation. The electro-carburisation involves a diffusion of carbon atoms into the surface of the metal which enhance the surface hardness of the metal. The effects of electrolysis parameters to the surface hardness and case hardening of treated metal have been reported in several journals. This article summarises the research findings. Apart from that, the quenching process and heat treatment post quenching also plays an important role in the quality of the carburised metal, therefore also reviewed in this article.

Steel is extensively used in many applications that include construction because of its unique properties and the ease with which its properties can be enhancedfor improved performance. Due to its high malleability and strength, it can be easily machined and welded compared to other types of steel. However, the susceptibility to low performance has been associated with its low resistance to environmental degradation when exposed to corrosive or polluted environments. This study focuses on mild steel heat treatment quenched in four mediums of engine oil, water, palm oil, and air, along with its properties and corrosion susceptibility. The high temperature used for the procedure is 800 °C, 900 °C, and 1000 °C, respectively. After the heat treatment procedure, the test samples undergo corrosion testing in the sodium chloride solution for two weeks to observe the presence of corrosion products rust on its surface. The tensile machine was utilized to obtain the mechanical properties, including yield strength, tensile strength, and percentage elongation. The hardness values were obtained using the Rockwell hardness machine, and the optical microscope (OM) was used to observe the effect of the corrosion activity on the sample surface. The results obtained indicate an increase in the hardness, yield, and tensile strength, but the elongation reduces as the temperature increases.

Heat Treatment Step

Friction surfacing is a solid state process and it is amenable for deposition of aluminum on steel. In this investigation, the mild steel surface was coated with a layer of aluminum using friction surfacing route. The aluminum thickness was in the range of 40-50 μm. It was followed by a heat treatment step to convert aluminum layer in to an aluminide layer. Heat treatment was done in open atmosphere at 700 °C for 2 hours. Microstuctural analysis showed that the aluminide layer is mainly made of Fe2Al5 and Fe4Al13, FeAl and Fe3Al are minor in fraction. Formation of Fe2Al5 is discussed. The aluminide layer also has some amount of porosities.
