Abstract
A high-speed electroforming technique that can produce an electroformed tool efficiently is developed to overcome a disadvantage of the conventional sediment codeposition technique that an extremely long time is required for the production of thick composite coatings. Aggregated diamond grain particles sedimented on a tool surface are agitated at a low speed with a rubber blade to increase the electric conductivity and to disperse the grain particles uniformly on the tool body. The time required to produce a thick nickel-diamond coating of 1 mm thickness is successfully reduced to 2.5 hours from the minimum of 81 hours required by the conventional sediment codeposition technique.
