Abstract

The invention belongs to the field of alloy manufacturing, and particularly relates to a wear-resistant corrosion-resistant multi-element manganese-aluminum bronze brazing alloy and a preparation method thereof. The wear-resistant corrosion-resistant multi-element manganese aluminum bronze brazing alloy is prepared from the following components in parts by weight: 7-10% of Al; 8-11% of Mn; 1.5 to3.0% of Fe; 1.5 to 2.5% of Ni; 0.005-0.03% of B; 0.05 to 0.1 of Y; 0.08-0.20% of La, and the weight ratio of the three elements of B to Y to La is 1: 10: 15-1: 3: 6, and other impurities are less thanor equal to 0.5 percent. The balance is Cu. The wear-resistant corrosion-resistant multi-element manganese-aluminum bronze brazing alloy disclosed by the invention is composed of Al, Mn, Fe, Ni, B, Y, La and Cu, the casting temperature is equal to or lower than 1050 DEG C, and the mechanical property is good. The alloy material is used for cladding an inner wall of a cylinder in a hydraulic support, has bright surface, less deformation, hardness of more than HB240, good wear resistance and corrosion resistance, the operation up to now has always been 2 times of the life of the original material, and the alloy material is still normally used.

Description

technical field [0001] The invention belongs to the field of alloy manufacturing, and in particular relates to a wear-resistant and corrosion-resistant multi-component manganese-aluminum bronze brazing alloy and a preparation method thereof. Background technique [0002] At present, the wear-resistant copper parts and their brazing materials used on cylinders, bearings, valves, rolls, etc. must adapt to harsh environments such as high temperature, dust, heavy load, corrosion, and wear. The materials used are generally aluminum bronze (such as ZQAL9-4, the composition is Al: 8-10%, Fe: 2-4%, and the rest is Cu), tin bronze (such as ZQSn10-1, the composition is Sn: 9-11%, P:0.6-1.2%, the rest is Cu), etc. The ZQAL9-4 alloy has a high dry grinding coefficient and poor thermal conductivity, and it is prone to "de-aluminumization" corrosion in the environmental medium, resulting in a low service life. However, ZQSn10-1 has lower strength and toughness, and its wear resistance i...
