Abstract

The invention relates to a machine manufacturing material, in particular to a high-performance piston manufacturing material. The material contains the following elements in percentage by mass: 11.0 to 13.0 percent of Si, 2.8 to 3.6 percent of Cu, 2.0 to 2.6 percent of Ni, 0.8 to 1.2 percent of Mg, 0 to 0.7 percent of Fe, 0.05 to 0.2 percent of Ti, 0 to 0.3 percent of Mn, 0.05 to 0.2 percent of Zr, 0.05 to 0.18 percent of V and the balance of Al. By proportioning the chemical components of the conventional piston manufacturing material more reasonably, the piston manufacturing material has qualitative leap; and compared with the conventional similar products, the piston manufactured by using the material has more excellent high-temperature mechanical strength, tensile strength and fatigue resistance and higher thermal stability and hardness, and meets various strict requirements of the conventional engine on the piston.

Description

technical field [0001] The invention relates to a mechanical manufacturing material, in particular to a high-performance piston manufacturing material. Background technique [0002] The piston is called the heart of the engine. It is one of the most important parts in the engine. Its function is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The working environment of the piston is very harsh, and the piston must withstand high temperature, high pressure thermal load and high mechanical load. Therefore, as a very important component of the engine for transferring energy, the piston must have the following properties: low density, light weight, good thermal conductivity, small thermal expansion coefficient, sufficient high-temperature mechanical strength, wear resistance, corrosion resistance, size Good stability. With the development of engine technology, pistons made of existing conventional pi...
