摘要： The present disclosure relates to a method for preparing a category of alloy powder and an application thereof. By selecting a suitable alloy system and melting initial alloy melt through low-purity raw materials, high-purity alloy powder, and matrix phase wrapping high-purity alloy powder are precipitated during the solidification process of the initial alloy melt, and the solid solution alloying of the high-purity alloy powder is achieved at the same time. Alloy powder can be obtained by removing the matrix phase wrapping the high-purity alloy powder; high-purity alloy powder can also be obtained by removing the matrix phase wrapping the high-purity alloy powder at an appropriate time. The method is simple and can prepare a variety of alloy powder materials with different morphology at nano-scale, sub-micron level, micron level, and even millimeter level.

摘要： A preparation method for a corrosion-resistant coating of a reinforcing steel for marine concrete, comprising the steps: (1) pretreating the surface of a reinforcing steel; (2) preparing self-repairing corrosion microcapsules; (3) preparing a cathodic electrophoresis coating; (4) carrying out cathodic electrophoresis; and (5) curing. The electrophoresis coating of the present invention contains the self-repairing corrosion microcapsules, metal powder, and graphene oxide powder. The corrosion resistance of the coating is improved under the co-action of the self-repairing properties of the self-repairing microcapsules and cathodic protection. The corrosion-resistant coating has excellent adhesion and corrosion resistance, prolonging the service life of reinforcing steel. It is widely used for the protection of reinforcing steels for marine concrete, and also for the protection of metal structures in general environment.

The present application provides a protective coating layer, including: a rusty-surface liquid layer, a nano-zinc yellow epoxy primer layer, a nano-epoxy micaceous iron oxide (MIO) intermediate coating layer, and a nano-fluorocarbon top coating layer, where the rusty-surface liquid layer is applied on a metal substrate; the nano-zinc yellow epoxy primer layer is applied on a surface of the rusty-surface liquid layer; the nano-epoxy MIO intermediate coating layer is applied on a surface of the nano-zinc yellow epoxy primer layer; and the nano-fluorocarbon top coating layer is applied on a surface of the nano-epoxy MIO intermediate coating layer. The present application effectively solves the technical problem that the existing protective coating layer with nanoparticles exhibits poor adhesion to a substrate and cannot provide a protective effect for a long time.

摘要： A propeller shaft (1) that is a power transmission shaft has a shaft member (2) as a tubular body made of iron-based metal and a balance weight (3) made of iron-based metal and welded to an outer peripheral surface of this shaft member (2). At least a part of the balance weight (3) of the propeller shaft (1) is covered with a sacrificial metal coating (4) made of sacrificial corrosion prevention material that contains metal whose ionization tendency is higher than that of metal forming the shaft member (2). With this, it is possible to suppress local progression of corrosion at a periphery of the balance weight (3) and improve durability of the propeller shaft (1).
