The properties of metals and alloys can be changed by heating followed by cooling under definite conditions to make them suitable for specific applications. Carburization is a method of producing mild steel having tough inner core and hard outer surface. Three Heat Treatment process namely Quenching, Carburizing and Tempering were done. The mild steels are carburized at temperature range of 850 to 950 oC and then it is tempered at 200 oC for thirty minutes after that it subjected for different kind of tests such as abrasive wear, hardness, tensile and toughness. The results indicated that the process of carburization greatly improves the mechanical and wear properties like hardness, tensile strength and wear resistance and these properties increases with increase in the carburization temperature but apart from this, the toughness property decreases and it is further decreases with increase in carburization temperature. The mild steels carburized at the temperature of 950 oC gives the best results for the mechanical and wear properties because at this temperature it gives the highest tensile strength, hardness and wear resistance, so it must be preferred for the required applications.
Author Keywords: Carburization, abrasive wear, weight loss, wear resistance and hardness.

Abstract
The properties of metals and alloys can be changed by heating followed by cooling under definite conditions to make them suitable for specific applications. Carburization is a method of producing mild steel having tough inner core and hard outer surface. Three Heat Treatment process namely Quenching, Carburizing and Tempering were done. The mild steels are carburized at temperature range of 850 to 950 oC and then it is tempered at 200 oC for thirty minutes after that it subjected for different kind of tests such as abrasive wear, hardness, tensile and toughness. The results indicated that the process of carburization greatly improves the mechanical and wear properties like hardness, tensile strength and wear resistance and these properties increases with increase in the carburization temperature but apart from this, the toughness property decreases and it is further decreases with increase in carburization temperature. The mild steels carburized at the temperature of 950 oC gives the best results for the mechanical and wear properties because at this temperature it gives the highest tensile strength, hardness and wear resistance, so it must be preferred for the required applications.
Author Keywords: Carburization, abrasive wear, weight loss, wear resistance and hardness.
