“…Surface hardening processes can impart many advantages such as high service life, high wear resistance at low cost [3,4]. One such surface hardening process is boronizing, a thermochemical surface treatment in which boron atoms diffuse into the surface of the work piece to form hard borides with the base material [5][6][7]. Corresponding to this, it has been shown that the borided steels exhibit high hardness (about 2000 HV), high wear resistance and improved corrosion resistance [8][9][10].…”

In this study, pack boronizing was applied to ash-blowing nozzles manufactured from AISI 1040 steels using Ekabor II powders as the boronizing source at a temperature of 1273 K for a duration of 8 h. Erosive wear tests of boride ash-blowing nozzles were carried out in ash delivery line of thermal reactor under actual working conditions. It was observed that erosive wear resistance of borided ash-blowing nozzles were increased 3 times as a result of the boronizing process. The improved wear resistance of the borided samples can be explained by increased surface hardness and higher work hardening.

The aim of this study is the investigation of the effect of ferroboron and ferrochromium with massive wire based hardfacing alloys. Mixture of Fe-Cr and Fe-B powders was added to massive wire during welding process. Hardface layers were obtained by three different powder mixture and three different powder/massive wire proportions. Hardfacing was applied to two AISI 1020 steel substrates by open arc welding. Hardness test, scanning electron microscope and X-ray diffraction analysis were made to the samples. Test results showed that increasing ferroboron content and increasing powder mixture amount enhanced the microhardness of the specimens.

“…The heat treatment and carburization increases the mechanical and wear resistance of the material In general, carburizing is the addition of carbon to the surface of low carbon steels at temperatures generally between 850 and 950 °C (1560 and 1740 °F) at austenite region that had high solubility for carbon and the stable crystal structure. Hardening is accomplished when the high carbon surface layer is quenched to form martensite so that a high carbon martensitic case will have good wear and fatigue resistance [4]. Carburizing steels for case hardening usually have base carbon contents of about 0.2%, with the carbon content of the carburized layer generally being controlled at between 0.8 and 1% C. However, surface carbon is often limited to 0.9% because too high a carbon content can result in retained austenite and brittle martensite.…”

Abstract:For most developing countries, including Ethiopia Agriculture is the backbone of their economy. Due to lack of effective farm implements, theses country's population has been suffering on food shortage. Hence, the major objective the study is to improve the mechanical properties and abrasion resistance of traditional farm implements. To achieve the intended objectives of the study, Investigation was conducted on the mechanical and wear characteristics of steel samples for better performance of farm implements subjected to packed carburization treatment using wood coal as the carburizer, carburized at 850 °C, 900 °C and 950 °C, soaked at the carburizing temperature for 1:50 hrs followed by quenched with water. At the first the test specimen for analysis of different mechanical and wear characteristics of various local farming tools like abrasive wear, toughness, tensile strength, abrasive wear and hardness were prepared as per ASTM standard. The test specimens that was prepared for this purpose was subjected to destructive mechanical test before and after carburization process. From the data obtained, ultimate tensile strength, percent elongation, percent reduction in area, modulus of elasticity, Rockwell hardness, impact toughness, and abrasive wear were calculated. The destructive mechanical test results are compared before and after carburization process in order to see the impact of pack carburization and carburizing temperature on the performance (life cycle )of the traditional farm implements. It was observed that the mechanical properties of steel samples were found to be strongly influenced by the process of carburization, carburizing temperature and soaking time at carburizing temperature. It was concluded that the sample carburized at 950 °C soaked for 1:50 hrs followed by water quenching gives best result than the other samples. Since pack carburizing enhance the hardness, tensile strength, abrasion resistance, the farm implement manufacturing company has been recommended to carburize these farm implement.
