Abstract

The invention discloses a composite metal material, which is characterized in that the composite metal material comprises the following components in metal quality percentage: 70 percent to 80 percent of iron used as a basic component, 4.7 percent to 6.2 percent of silver powder, 5.6 percent to 7.7 percent of zinc powder, 4.3 percent to 6.5 percent of aluminum powder, 3.2 percent to 4.9 percent of magnesium powder, 1.3 percent to 3.7 percent of copper powder, 0.15 percent to 0.25 percent of ball-milling chromium powder, 0.13 percent to 0.27 percent of manganese powder, 0.2 percent to 0.35 percent of molybdenum powder, 0.13 percent to 0.25 percent of cobalt powder, 0.13 percent to 0.25 percent of graphite powder, and 0.05 percent to 0.12 percent of molybdenum disulphide powder. The invention provides the composite metal material, which has excellent friction performance, lower friction coefficient, small erosion, and better thermal conductivity.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a composite metal material. Background technique [0002] Various mechanical parts made of metal materials are often subjected to various forms of external forces during use. As a result, they may be subjected to impact, tension, pressure, bending, torsion, etc.; Normal operation requires that the metal material must have a certain ability to resist external forces without deformation or damage. The performance of metal materials against external forces is called the mechanical properties of metal materials. The commonly used indicators mainly include strength, plasticity, hardness, impact toughness, fatigue strength, creep and relaxation. The materials currently used are extremely easy to wear, have poor thermal conductivity, and are prone to high-temperature friction and deformation. Contents of the invention [0003] In view of the deficiencies in the above technologies, the...
