Abstract:

The thermal-diffusion surface process is defined in the German Industrial Standard DIN 17014 as a thermal chemical heat process made to enrich the surface of the work piece with a bor. In other words, bor atoms can be defined as forming pipe structures with the main material atoms as a difuze from the surface to the inside of the metal workpiece. When applied to the appropriate materials, it provides stretching and drilling resistance. Drying is high against some acids and hydrochloric acid also provides partial resistance, can be applied to shaped parts and increases the livelihoods. The liquid bed contains a liquid-hard mixture that shows the liquid characteristics. Fluid beds are used in technology to connect at high values between gases and solids. Fluid bed oven is a vertical cylindrical-shaped unit powered by air from the bottom, with many advantages compared to other heat processing sources. While working, it is similar to the same welding liquid bath, which quickly provides a equal heat transfer in all directions. Fluid bed oven provides cheap processing costs and safe usability. Gas, liquid, pasta, box and plasma piping, which are traditional methods, has a variety of disadvantages, and has advantages such as fluid bed oven piping, economic efficiency compared to traditional methods, low processing time and very good heat transfer. In this study, 90MnCrV8 studied the changes in the pipeline layers resulting from the welding of the cool work cluster steel at 850-950 and 1050°C at an intrinsically heated liquid bed in 1 and 4 hours.
