Abstract

The invention relates to a plating cavity capable of improving uniformity of a Ni-SiC composite coating of an inner wall of a hollow workpiece. An electroplating anode is placed on the upper surface of a base of the plating cavity, and the lower end of the electroplating anode is embedded into an anode groove in the upper surface of the base of the plating cavity. An electroplating cathode is mounted on the electroplating anode in a sleeving manner and the lower end of the electroplating cathode is embedded into a cathode groove in the upper surface of the base of the plating cavity. A top cover of the plating cavity is supported through the electroplating cathode and the electroplating anode. The Ni-SiC composite coating is plated in a sealed condition and the uniformity of a Ni-SiC composite plating solution in a flowing state in the plating cavity and the degree of dispersion and uniformity of SiC particles can be improved effectively, so that the integrity and uniformity of the Ni-SiC composite coating prepared on the inner surface of the hollow workpiece are further improved effectively.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a plating cavity capable of improving the uniformity of the Ni-SiC composite coating layer on the inner wall of a hollow part. Background technique [0002] At present, in the field of domestic construction machinery, the traditional immersion production process is generally used in electroplating. In addition to the adverse effects of the open production method on the service life of the plating solution and the safety and health of related workers, this process technology is There are also problems such as low particle utilization, uneven distribution in the coating, and high sealing requirements when performing composite electroplating. Therefore, it is an inevitable trend in the development of electroplating technology to design new electroplating devices, update and optimize traditional electroplating production processes, and realize green, environmentally friendly, energy-sa...
