Title:
SHOT BLASTING AND ELECTRODEPOSITION MANUFACTURING METHOD AND APPARATUS FOR THREE-DIMENSIONAL SURFACE
Document Type and Number:
WIPO Patent Application WO/2018/006434
Kind Code:
A1
Abstract:
Provided are a shot blasting and electrodeposition manufacturing method and apparatus for a three-dimensional surface. A deposition solution is mixed with a hard particle, and is then deposited, via blasting, onto a conductive substrate (2) to realize a rapid manufacturing technique for electrodeposition, reduce a crystal growth rate of an electrodeposition process, achieve the goal of fine crystal grain size, and significantly improve the quality of a deposited layer. Combining the two processes can effectively overcome defects of hydrogen generation at a cathode and loose texture, patches, and dents on the deposited layer as a result of contaminant adhesion, thereby improving hardness and compactness. A 5-axis interlocking numerical control processing system is incorporated to achieve processing in a three-dimensional space to improve the uniformity of the deposited layer and the precision of a shape. The method can be widely applied in the production of a precious metal item and a component with a complex shape, and can also be used for a rapid surface coating and strengthening technique.
