LOCAL ELECTRIC ARC METALLIZATION METHOD FOR EXTENDING THE SERVICE LIFE OF SUBMERSIBLE ELECTRIC MOTORS

Annotation. The issue of increasing the time between overhauls of submersible electric pumps operating in aggressive reservoir environments remains highly relevant for the oil production industry. Existing repair methods typically require complete disassembly of the equipment or do not provide the necessary durability of protective coatings. The article proposes a method for local restoration of corrosion damage to the outer surface of a submersible electric motor (SEM) housing during routine repair using electric arc metallization. Optimal technological parameters are determined to form a coating with high adhesive and protective properties. It is shown that preliminary abrasive surface activation and layer-by-layer application of a metallization layer made of corrosion-resistant alloys ensure restoration of the housing geometry without stator disassembly due to minimal thermal impact. Examples of practical implementation of the method are provided, confirming its effectiveness for extending equipment service life. The expected economic effect from implementing the technology is a 3–5 times reduction in repair costs compared to complete housing replacement.

Keywords: submersible electric motor, corrosion, electric arc metallization, renovation, protective coatings, stainless steel, aluminum-zinc alloy.
