The disclosure provides a powder sherardizing agent, anti-corrosion metal part and sherardizing method. The powder sherardizing agent in parts by mass includes 20-100 parts of a metal powder, 40-80 parts of a dispersing agent, 0.2-5 parts of decomposing agent. The metal powder includes 60-97 parts of zinc powder and 3-40 parts of magnesium powder. The powder sherardizing agent provided by this disclosure can realize the infiltration of magnesium during the sherardizing process. Zinc and magnesium can form a zinc-magnesium alloy phase with high corrosion resistance, thereby greatly improving the corrosion resistance of the infiltration layer. The sherardizing method provided by this disclosure has the advantages of simple operation, convenient use, low cost, high economic benefit, and wide application range.

A sliding member includes a carbon transfer layer and can superiorly effectively decrease friction and reduce wear. A method produces the sliding member. The sliding member includes a substrate and a carbon transfer layer. The carbon transfer layer is disposed on the surface of the substrate and includes both sp.sup.2 bonded carbon and sp.sup.3 bonded carbon. The carbon transfer layer preferably has a ratio sp.sup.3/(sp.sup.2+sp.sup.3) of the sp.sup.3 bonded carbon to the totality of the sp.sup.2 bonded carbon and the sp.sup.3 bonded carbon of 0.1 or more.

A method for forming an impact weld used in an additive manufacturing process. The method includes providing a wire having a powder filler metal core located within a sheath. The wire is then inserted within a conduit having an opening. Further, the method includes providing at least one energy pulse that interacts with the sheath to pinch off at least one segment of the wire, wherein the energy pulse causes propulsion of the segment toward a substrate with sufficient velocity to form an impact weld for welding the metal core to the substrate. In particular, the energy pulse is an electromagnetic pulse, a laser energy pulse or a high electric current pulse.
