摘要:

AbstractThe advantages of powder coating techniques over traditional paint systems are reviewed with reference to Nylon 11 (Rilsan) coatings. The physical, electrical, and chemical resistance properties of such coatings are summarized, and component design for surface coating is discussed. After consideration of surface preparation requirements, the advantages of three application techniques, fluidized bed coating, electrostatic spray coating, and flame spraying, are covered, particular attention being given to flame spraying since the fact that it can be used easily on site suggests widespread future usage. A brief discussion of current industrial applications of flame sprayed nylon coatings is followed by some thoughts on the future development of the process.

摘要:

AbstractA chromium–nickel austenitic stainless steel was plasma nitrided at 535, 585, 650, 735, and 785°C. After nitriding, the structure, thickness, and hardness of the surface layer, as well as the appearance and height of surface irregularities, were determined. The wear and corrosion resistance of the nitrided steels were tested and the percentage of magnetic phases present was determined. It has been established that nitriding markedly raises the wear resistance of the steel at pressures of 50, 200, and 400 MPa. The corrosion resistance of the steel in 0.05 M Na2SO4at pH 3 decreases as a result of nitriding. Nitriding leads to the appearance of a multi phase structure in the surface layer, the proportion of the ferromagnetic a andγ’phases being dependant on nitriding temperature. After nitriding at 785°C the proportion of these phases is minimal. At the same time, the steel has a high hardness and wear resistance and is susceptible to passivation.

摘要:

AbstractThe surface of nodular cast iron was first coated with tungsten carbide powder, then melted by concentrated solar energy to form an alloyed layer on its surface. By scanning a high energy focal point over the surface, a predominantly alloyed surface was created after rapid solidification. The surface of the alloyed layer was quite flat, with a microstructure of very fine ledeburite. This alloyed layer possessed a very high hardness and high tempering resistance, and had greatly improved wear resistance compared to untreated nodular cast iron. In addition, excellent adhesive wear resistance is displayed by the alloyed material.
