A coating/repairing process using electrospark with PSP rod

摘要

An electrospark deposition electrode (20) and an associated method for depositing coatings using the electrode are provided. The electrode includes a powder of a first metal (36) and a powder of a second metal (38). The second metal (38) is a braze alloy including nickel, the second metal (38) having a lower melting point than the first metal (36). The powder of the first metal (36) and the powder of the second metal (38) are sintered together to form the electrode (20) so that the powders are comingled but not combined within the electrode (20). The method includes depositing a layer of the first metal (36) onto the substrate using an electrospark deposition process.
