摘要： The present invention relates to a composite metal material and a low-temperature solder paste with high thermal conductivity containing the same. The composite metal material is a Cu core/Ag intermediate layer/Sn shell type metal powder (Cu@Ag@Sn) or a Cu core/Ni intermediate layer/Sn shell type metal powder (Cu@Ni@Sn) with a particle size of 20-60 μm. The low-temperature solder paste with high thermal conductivity is obtained by mixing the composite metal material with an Sn—Bi series alloy powder and a flux paste, can be used for welding of a variety of substrate, and is suitable for welding at a low temperature of lower than 150° C. The composite metal material of the present invention has a simple process, a low cost and high practicability, and poor heat dissipation and other problems of power devices after die bonding caused by low thermal conductivity of current solder pastes on the market are solved.

摘要： A method is provided to remove a selective amount of material from a metal component fabricated by additive manufacturing in a self-terminating manner. The method can be used to remove support structures and trapped powder from a metal component as well as to smooth surfaces of a 3D printed metal component. In some embodiments, selected surfaces of the metal component are treated to make the selected surfaces at least one of mechanically and chemically unstable. The unstable portion of the metal support can then be removed chemically, electrochemically, or through vapor-phase etching. The method can be used for processing any fluid or vapor-accessible regions and surfaces of a 3D printed metal component.

摘要： The present invention relates to a preparation method of a copper green rust pigment, particularly a preparation method of a copper green rust pigment that can replace the traditional Dancheong Hayeob pigment comprising the following steps: a step of preparing a copper powder comprising at least one of copper; and a copper alloy comprising copper and at least one of tin (Sn), zinc (Zn), and lead (Pb); and a step of corroding the copper powder by mixing the copper powder with a corrosive agent containing sodium chloride and ammonium chloride. The corrosive agent includes 75 to 90 weight % of the sodium chloride and 10 to 25 weight % of the ammonium chloride based on the total weight.
