Abstract

The invention discloses a method for repairing titanium alloy damaged parts by electroless nickel plating, comprising the steps of degreasing→protection→blowing abrasives→white ash degreasing→activation treatment→hydrogenation treatment→electroless nickel plating→heat treatment. The invention is a new process method for repairing the dimensions of titanium alloy damaged parts by chemical nickel plating, which solves the problem of repairing the bonding force of damaged parts, and is a key technology for repairing the size of damaged titanium alloy parts of Su-27 and Su-30 aircraft by electroless nickel plating According to the invention, the electroless nickel plating of damaged titanium alloy parts can be completed to meet the needs of guaranteeing the repair of damaged titanium alloy parts of Su-27 and Su-30 aircrafts, and has great popularization value.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and relates to a new process method for repairing dimensions of titanium alloy damaged parts by electroless nickel plating. Background technique [0002] Conventional electroless nickel plating process for Su-27 and Su-30 aircraft titanium alloy damaged parts cannot solve the problem of dimension repair of titanium alloy damaged parts. After retrieval, there is no electroless nickel plating repair process for titanium alloy damaged parts in the domestic voyage repair system, and there is no public process technology. The technical problem solved by the invention is the size repairing process of titanium alloy damaged parts of Su-27 and Su-30 aircraft, which can complete the repair of titanium alloy damaged parts in a certain range and meet the needs of repairing titanium alloy damaged parts. Contents of the invention [0003] A method for repairing titanium alloy damaged parts by ele...
