The structural and phase transformation of microarc oxidation (MAO) coatings on 6061 aluminum alloy at 300∘C/3[Formula: see text]MPa steam were evaluated. After 10 days steam corrosion, the weight loss of coated alloys with 15[Formula: see text][Formula: see text]m and 75[Formula: see text][Formula: see text]m thickness was only about 1/10 and 1/50 of weight gain of bare alloy, respectively. The [Formula: see text]-Al2O3 and [Formula: see text]-Al2O3 phases in the MAO coatings were stable at 300∘C/3[Formula: see text]MPa steam, but many fine needle-like or brick-like boehmite crystalline particles also appeared on coating surface. The boehmite had a large influence on the permittivity of coatings at low frequency. The MAO treatment on 6061 aluminum alloy improved its corrosion resistance at high-temperature and high-pressure steam.

Abstract EASTERN STAINLESS Type 347 contains an addition of columbium which produces a stabilized type of stainless steel free from the chromium carbide precipitates that cause intergranular corrosion. It is recommended for welded parts which cannot be annealed after welding. It is also used for parts which are intermittently heated and cooled to temperatures between 800 and 1600 F. Its many applications include exhaust manifolds, expansion and high-pressure steam pipes. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-390.

Valve Sealing

Laser cladding technology is highly suitable for the remanufacturing of thin-walled and easily deformable parts due to its concentrated energy density. Due to the high temperature and high pressure corrosion environment, the valve sealing surface is prone to corrosion, wear and other failures. A nickel-based tungsten carbide alloy layer was prepared on the valve sealing surface substrate material by laser cladding process. By designing orthogonal experiments, the effects of laser power (P), scanning speed (Vb), powder feeding rate (Vf), and WC content (wt%) on the alloy layer were investigated. A fuzzy comprehensive evaluation method including macroscopic quality, microstructure, microhardness, anti-wear performance, oxidation resistance, compactness and corrosion resistance was proposed. The experimental results showed that the hardness, oxidation resistance and corrosion resistance of the laser alloy layer are significantly improved compared with the matrix; the optimum process parameters and the addition ratio of WC powder are laser power (P) of 1.1 kW and scanning speed (Vb) of 800 mm/min. The powder feeding rate (Vf) was 20%, and the WC content was 20% by weight.
