Only samples 3 and 8 were broken on the retreating side. The tensile strength values of different samples are presented in Table 3.

Int J Adv Manuf Technol 61(1–4):195–204, Magnabosco I, Ferro P, Bonollo P, Arnberg L (2006) An investigation of fusion zone microstructures in electron beam welding of copper- stainless steel. The metallographic organization of H62 copper alloy modified layer was analyzed using an MDS400 inverted metallographic microscope produced by Chongqing aut Optical Instrument Co., Ltd (China).
For example: Brass is usually a warm golden color. The brass supplier from China default brass option is H59. In comparison, bronze is principally an alloy of copper and tin.

This was because the higher the pressure during the modification process, the higher the temperature, and the more refined the grain, the finer the grain. Hence, the tensile strength was larger. Wang14 et al. | All Rights Reserved. Therefore, the grain size was refined by increasing the temperature. Brass H62 consists mainly of two elements: copper and zinc; copper accounts for 62%.

Figure 3((d) to (f)) shows that under the same technological parameters, the grain refinement degree on the surface of the modified layer increased with the increase in pressure and the grain size of the modified layer after two passes of modification. Defects such as pores, cracks, and oxides often exist in the coating tissues obtained by plasma spraying, which to a large extent limit the application of plasma spraying technology.16 Li17 et al. The higher the copper content, the higher the unit price and the lower the copper content, the lower the unit price.

The surface of copper alloy was modified to improve its wear resistance, corrosion resistance, and tensile strength. The elements in stainless steel and brass had homogeneous distribution and mixing.
The preliminary test force of the head was 10 kg, the main test force was 90 kg, the total test force was 100 kg, and the loading and unloading time was 10 s. Each test point selected three points near its center and took the mean as the hardness value of this point. The study adopted the NN universal tensile testing machine produced by Shanghai New San Si Measuring Instrument Manufacturing Co., Ltd. (China) for stretching experiments and S-3400N tungsten filament scanning made by Japan Hitachi Co., Ltd. Five tensile samples were selected under each parameters, and the average value of the tensile values of the five samples was taken as the tensile value of the tensile samples under this parameter.
