Abstract: A coating process for applying a bifurcated coating to an article is disclosed including applying an aluminizing slurry to a first portion of the article, applying a chromizing slurry to a second portion of the article, and simultaneously heat treating the article, the aluminizing slurry, and the chromizing slurry. Heat treating the aluminizing slurry forms an aluminide coating on the first portion of the article and an aluminide diffusion zone between the article and the aluminide coating. Heat treating the chromizing slurry forms a chromide coating on the second portion of the article and a chromide diffusion zone between the article and the chromide coating. The first portion and the second portion are both maintained in an unmasked state while applying the aluminizing slurry and the chromizing slurry and during the heat treating.

Abstract: The present invention discloses a rare earth permanent magnet and a method for preparing same. The material of the rare earth permanent magnet has a heavy rare earth element volume diffusion phenomenon at a depth of 5 μm to 100 μm from the surface of the magnet to the interior of the magnet along the magnetic field orientation direction, thereby forming a volume diffusion layer region; the volume diffusion layer region is divided into magnet units having a volume of 10*100*5 μm, and the concentration difference of the heavy rare earth elements of the magnet units at different positions in the volume diffusion layer is below 0.5 at %. The present invention provides a sintered NdFeB magnet of high intrinsic coercive force Hcj on the premise of not influencing the remanence Br and the maximum magnetic energy product (BH)max of products. In the method for preparing the rare earth permanent magnet, microwave heat treatment is performed on a blank magnet coated with heavy rare earth source slurry in a vacuum condition. This method can effectively improve the heating efficiency, reduce the heat treatment time, lower the energy consumption, and reduce the production cost of the magnet.

Abstract: The present disclosure relates generally to hardface coating systems and methods for metal alloys and other materials for wear and corrosion resistant applications. More specifically, the present disclosure relates to hardface coatings that include a network of titanium monoboride (TiB) needles or whiskers in a matrix, which are formed from titanium (Ti) and titanium diboride (TiB2) precursors by reactions enabled by the inherent energy provided by the process heat associated with coating deposition and, optionally, coating post-heat treatment. These hardface coatings are pyrophoric, thereby generating further reaction energy internally, and may be applied in a functionally graded manner. The hardface coatings may be deposited in the presence of a number of fluxing agents, beta stabilizers, densification aids, diffusional aids, and multimode particle size distributions to further enhance their performance characteristics.

Abstract: A surface of an article is modified by first disposing a nickel-enriched region at the surface of a substrate, then enriching the nickel-enriched region with aluminum to form an aluminized region, and finally removing at least a portion of the aluminized region to form a processed surface of the substrate. Upon removal of this material, the roughness of the surface is reduced from a comparatively high initial roughness value to a comparatively low processed roughness value. In some embodiments, the processed roughness is less than about 95% of the initial roughness. Moreover, the sequence of steps described herein may be iterated one or more times to achieve further reduction in substrate surface roughness.

Abstract: Producing an RFeB system sintered magnet with high corrosion resistance and low loss of energy in an RFeB system sintered magnet with high magnetic properties produced by a grain boundary diffusion process. A paste prepared by mixing an organic matter having a molecular structure including an oxygen atom and a metallic powder containing a heavy rare-earth element which is at least one element selected from the group of Dy, Ho and Tb, is applied to the surface of an RFeB system sintered compact composed of crystal grains whose main phase is R2Fe14B containing, as a main rare-earth element, a light rare-earth element which is at least one element selected from the group of Nd and Pr. A heating process for a grain boundary diffusion treatment is performed. As a result, a protective layer containing an oxide of the light rare-earth element is formed on the surface.
