The invention relates to the technical field of remanufacture and discloses an induction-cladding sleeve part inner wall remanufacturing method. The induction-cladding sleeve part inner wall remanufacturing method comprises the following steps of (a) cleaning and preprocessing the surfaces of the inner walls of sleeve parts, (b) pre-arranging iron-base alloy powder coatings on the surfaces of the inner walls, (c) preparing high-frequency induction-cladding coatings and (d) machining the induction-cladding coatings. The induction-cladding sleeve part inner wall remanufacturing method has the advantages that good alloy bonding is formed between the prepared induction-cladding remanufacturing coatings and part base bodies; a heat affected zone in the remanufacturing machining process is narrow, and no heat damage is produced to the base bodies. nickel base, iron base, cobalt base or light alloy coating materials can be selected to perform remanufacturing repair according to the actual service conditions, failure modes and material characteristics of the inner walls of the parts; high-frequency induction heating is utilized to provide a fusion-covering heat source for induction-cladding sleeve part inner wall remanufacturing, no wastewater, waste gas and waste residue causing pollution is produced in the remanufacturing process, and no harm caused by noise, dust, radiation, strong light and the like is brought to an operator.
