Coloring method for red spot copper

Номер: CN102899647A
Автор: Zhu Xinkun, Long Yan, Gong Yulan, Ren Shiying, Wu Xiaoxiang
Принадлежит:

The present invention relates to a coloring method for a red spot copper, and belongs to the field of metal material surface treatment and handicraft product production. The coloring method comprises: selecting a copper-zinc alloy casting having a copper content of 97-93%, carrying out a coloring pre-treatment, placing the casting in a spot emergence solution to carry out erosion for 5-10 minutes to emerge spots, and placing the spot emerging casting in a coloring solution to soak for 8-10 hours to appear red, wherein a specific time can be controlled according to color requirements of the specific handicraft product, and the longer the soaking time in the solution is, the more significant the red coloring effect is. The preparation method has the following advantages that: operation is simple; production cost is low; a production period is short; no product shape limitation exists; the product has a beautiful color; and the like.

Принадлежит:

The invention provides a high strength superfine crystalloid copper-germanium alloy and a preparation method thereof. The high strength superfine crystalloid copper-germanium alloy consists of the following components in percentage by mass: 99.89 to 89.85 percent of copper, and 0.11 to 10.15 percent of germanium. The preparation method comprises the following steps of: mixing pure copper and pure germanium in the proportion, smelting, and casting into a copper-germanium alloy bar; performing vacuum annealing, and forging; performing vacuum annealing again to obtain a homogenous microstructure; and immersing in liquid nitrogen for cooling, and forging to obtain the deformation twins-containing high-strength superfine crystalloid copper-germanium alloy. The stacking fault energy of the copper is reduced by adding the germanium element, and a large quantity of deformation twins are introduced, so that the copper-germanium alloy has high strength and excellent mechanical properties. Through ...
