The Heat Treatment and Carburization has been acknowledged by some means of improving the various properties of metals and alloys. For this investigation before heat treated , heat treated and carburized mild steel were selected. Three Heat Treatment process namely Quenching, Carburizing and Tempering were done. In the present investigation the Mechanical and Wear behaviours of mild steels Carburized at 860 0 C different Soaking time 2 hour(120min), 2 hour 30 minutes(150min) and 3 hour(180min). The aim has been to examine the effects of these different Soaking Time and conditions on the Mechanical and Wear properties of the Carburized mild steels. For above purpose firstly the mild steels are carburized at 860 0 C temperature and then it is Tempered at 200 0 C for 1 hour after this the Carburized and Tempered mild steels are subjected for different kind of test such as Abrasive Wear Test, Hardness Test and Tensile Test. Abrasive Wear behaviour of these mild steels was investigated by using the Dry Sand Abrasion Test Rig (TR-50) Machine. This paper further examines the effect of soaking time, applied load and abrasive wear behavior of carburized mild steel have been studied in detailed

“…(4) The effective case depth governed by carburization temperature, time, the carbon content of steel, and the carbon potential of atmosphere is calculated, and a simple and practical set of guidelines for optimizing gas carburization has been provided for plant production. Aramide et al (5) studied the effects of the carburization temperature and time on the mechanical properties of mild steels carburized with activated carbon, and observed that the mechanical properties of mild steels were strongly affected by the process of carburization, carburization temperature, and soaking time at the carburization temperature. They concluded that the optimum combination of mechanical properties is achieved at the carburization temperature of 900 ℃ followed by oil quenching and tempering at 550 ℃.…”

The manufacturing processes of timber screws, which are widely used for wood construction work, include wire manufacturing, heading and threading, case treatment, and coating. A lowcarbon steel wire of AISI 1022 is used to easily fabricate timber screws. The majority of case treatment activities are performed to improve the screw strength without affecting the soft, tough interior of the screws in drilling operation. In this study, the Taguchi method is used to obtain optimum case treatment conditions to improve the mechanical properties of AISI 1022 timber screws. The quality of case-treated timber screws is affected by various factors, such as case treatment temperature, case treatment time, atmosphere composition, and tempering temperature. The effects of case treatment parameters affect the quality characteristics, such as case hardness and torsional strength. It is experimentally revealed that ammonia flow rate, case treatment time, and carbon potential are significant for case hardness, while methanol flow rate, case treatment temperature, and case treatment time are significant for torsional strength. The optimum mean case hardness is 673.1 HV, the optimum mean core hardness is 440.0 HV and, for torsional strength, the optimum mean value is 5.3 N⋅m. The new case treatment parameter settings evidently improve the performance. The strength of the case-treated AISI 1022 timber screws is effectively improved. These results may be used as a reference for fastener manufacturers.

The effective case depth (ECD) plays an important role in the meshing strength of internal gear transmissions. Carburizing quenching heat treatment is commonly used to enhance gear strength and wear resistance. However, the different ECDs in internal and external gears caused by heat treatment significantly affect the meshing strength, causing vibration, reducing gear service life, and hastening malfunction in internal gear transmission. In this study, we conducted an investigation of different ECDs by the heat treatment of carburized gear pairs by numerical simulation with the finite element method (FEM) and experiment tests. We analyzed three different carburized layer models, with the ECD in the internal gear being greater than, less than, and equal to the ECD in the external gear. In addition, we investigated the ability to distinguish between hardness gradients in gear teeth by dividing the carburized depth into seven layers to improve modeling accuracy. Results revealed that the meshing strength of internal gear transmission could be significantly enhanced by adopting the model with the ECD in the internal gear being less than the ECD in the external gear, and moreover, the shear stress of carburized gears initially increased and then decreased along with depth direction, and the maximum value appeared in the middle of the lower surface.
