Abstract
The paper investigates wear resistance and corrosion resistance of protective coatings of D16 aluminum alloy under conditions that simulate operation of drill pipes. The paper also presents microstructure of coatings, electrochemical potential and corrosion rate of D16 aluminum alloy with various coatings. We evaluated adhesion and wear resistance of these coatings. D16 alloy with a tungsten carbide coating has the widest range of service properties and can be used to effectively protect the surface of aluminum drill pipes during operation operation.
Highlights
Development of oil and gas industry leads to constant complication of well drilling conditions, which requires the use of new materials for the manufacture of drill pipes and their reasonable choice for specific conditions [1,2,3,4,5]
Despite having significant advantages, including corrosion resistance [11,12], aluminum drill pipes are inferior to steel ones in terms of wear resistance
As there is no information in scientific literature on the effect of protective coatings on the properties of aluminum drill pipes, the research can be considered as a topical one
Summary
Development of oil and gas industry leads to constant complication of well drilling conditions, which requires the use of new materials for the manufacture of drill pipes and their reasonable choice for specific conditions [1,2,3,4,5]. Research has shown the advantages and prospects of using aluminum alloys (in comparison with steels) as a drill pipe material in the development of oil fields [610]. Despite having significant advantages, including corrosion resistance [11,12], aluminum drill pipes are inferior to steel ones in terms of wear resistance. The most economical one is the use of protective coatings for pipe metal. As there is no information in scientific literature on the effect of protective coatings on the properties of aluminum drill pipes, the research can be considered as a topical one. The aim of this work is to study the effectiveness of various protective coatings that can improve performance properties of aluminum alloys used for the manufacture of drill pipes
