Grain shape as a factor governing the parameters of diamond electroplated coating of dressing tools. Part 2. Actual grain–graphite form contact area and related characteristics as input data for calculating the conditions of diamond electroplated coating application by electroforming method

Аннотация

The paper gives experimental data on the actual contact area between grains and the graphite form used in the process of deposition of a diamond coating onto a dressing tool by the electroforming method. Also, the authors provide the results of determination of the maximum section of diamond grains in the powders of different grain sizes, the specific number of grains on the surface and their orientation—the data needed for the calculation of the free surface area of nickel being deposited, and thus the deposition rate and time as well as the final thickness of the diamond electroplated coating.
