The latest information on 7075 and 7075 aluminum rods on January 30. In the early part of the twentieth century, many grades of aluminum were developed due to its invention. The structure and properties of the 7075 aluminum rods in paper are affected by the vanadium infiltration process in a TD salt bath with surface coating treatment (thermal diffusion). The research results show that the 7075 aluminum rod TD salt bath vanadium infiltration was treated for 5h and oil quenched at 1223K, and the age was 453K for 2h. The coating is mainly made of vanadium carbide, and its thickness and microstructure are uniform and dense, respectively. At the same time, the resulting coating exhibited an ultra-high surface microhardness of 2586 HV.
We call this function as a rheological property, in which the fluid magnetic abrasive (FMA) can be performed due to the workpiece. Based on the study of microstructured fluid magnetic abrasive (FMA), experimental results are presented in this paper. In response to this problem, the current vacuum casting method of 7075 aluminum rod products lacks the ability to fill the thin-walled castings.
Therefore, a regulated vacuum pressure casting method is proposed to utilize the regulated pressure to improve the filling capacity. The process and mechanism of adjusting the pressure vacuum casting method was proposed and proved by self-made 7075 vacuum casting prototype. The results show that the adjusted pressure vacuum casting method has a higher filling capacity and can provide a higher negative pressure throughout the filling process. Therefore, the regulated pressure vacuum casting method has deep development potential. Then the abrasion resistance properties of 7075 aluminum rods were greatly improved. In addition, the research results show that the effect of vanadium salt treatment on the surface roughness of 7075 is not obvious
