Embodiment 1

[0020] The wearing plate of the support base of the present invention uses a shape memory alloy as a base body, a titanium coating layer is provided on the outer surface of the base body, and a coating film is provided on the outer surface of the titanium coating layer.

[0021] The composition of the shape memory alloy is as follows: 2at% manganese, 0.2at% neodymium, 48at% titanium, 46at% nickel, 2at% iron, 1at% molybdenum and 0.8at% chromium.

[0022] The mass content of the titanium coating is as follows, C: 0.03%, Si: 0.05%, Mn: 0.5%, P: 0.050%, S: 0.005%, Nb: 0.010%, N: 0.004%, Al: 1%, The balance is Fe.

[0023] The coating film is a compound composed of silanol-based vinyl copolymer resin particles, silicon dioxide particles, organic titanium compounds and phosphoric acid compounds.

[0024] Among them, silanol-based vinyl copolymer resin particles are used: alkali metal hydroxide (potassium hydroxide, sodium hydroxide), ammonia water, organic The amines are neutraliz...

Abstract

The invention discloses a supporting base wearing plate. With shape memory alloy as a matrix, the outer surface of the matrix is provided with a Titanium-plated coat, and the outer surface of the Titanium-plated coat is provided with a coated film. Rigidity, yield strength, strength of extension and impact resistance of the shape memory alloy is improved by adding high purity neodymium rare earth elements; compared with iron nickel titanium molybdenum shape memory alloy with a same percentage of iron atom and molybdenum atom, the adopted shape memory alloy has higher strength and corrosion-resistant performance at a temperature of -150DEG to +150 DEG C; the adopted shape memory alloy can bear big load action, has high security coefficient and prolongs service life; the coated film arranged on the outermost layer can improve corrosion-resistant performance, solvent resistance and oil resistance of the material itself, and is suitable for being applied to a position in which service environment is complex such as a bearing, supporting base and the like. Among them, properties of the coated film are affected when titanium atom content is too low, while too high content causes inferior compactness, thus proper content needs to be controlled.

Description

technical field [0001] The invention relates to an accessory for railway wagons, in particular to a wearing plate of a support seat. Background technique [0002] As an important carrier of freight transportation, the performance of railway freight cars is directly related to whether the goods are transported smoothly and can arrive on time; due to the large carrying capacity of freight cars, the performance requirements of each component are relatively high. As an important load-bearing part of the support seat, the wear plate of the support seat bears pressure from the front of the support seat and impact forces from different directions, requiring it to have good hardness, strength and impact resistance. Existing wear plates for support seats are mainly made of nodular cast iron or ordinary carbon steel after being strengthened by a heat treatment process, but generally after the heat treatment process, cracks and other defects are prone to occur, which affects the servic...
