Description

Metal steel ring in steel belt assembly for continuously variable transmission and preparation method thereof
Technical Field
The invention relates to a metal steel ring in a steel belt component for a continuously variable transmission and a preparation method thereof.
Background
The stepless speed changer has the advantages of good stability, no uncomfortable feeling of abrupt acceleration and light weight, but also has the problem of great manufacturing difficulty. The steel belt assembly is one of the core components of the continuously variable transmission and consists of a push plate and metal steel rings placed on two sides. The metal steel ring is formed by superposing a certain number of annular thin steel sheets, and the number is changed according to the model, and is generally 6, 10 and 12. The mass of the steel ring affects not only the transmission torque of the transmission, but also its service life. When the continuously variable transmission works, the metal steel ring is subjected to alternating stress and is worn with the pushing piece, so that the main failure modes of the metal steel ring are fatigue fracture and wear. Therefore, it has been studied to improve the wear resistance and fatigue strength.
Disclosure of Invention
The invention provides a metal steel ring in a steel belt component for a continuously variable transmission and a preparation method thereof, and aims to solve the problems that the abrasion resistance between the metal steel ring and a push plate in the steel belt component for the continuously variable transmission is insufficient and fatigue damage is easy to occur in the prior art.
The technical scheme of the invention is as follows:
a metal steel ring in a steel belt assembly for a continuously variable transmission is formed by welding a general 18 Ni-series maraging steel having a laser-textured pattern on both surfaces in a strip shape into a ring shape, and depositing (CoCrFeNiAl X Ta Y )N Z The high-entropy alloy film is manufactured;
the general 18Ni series maraging steel comprises the following specific components in percentage by mass: 16-19% of nickel, 10-13% of cobalt, 4-6% of molybdenum, 1-2% of titanium, less than 0.2% of aluminum, less than 0.02% of carbon, less than 0.01% of silicon, less than 0.001% of sulfur, less than 0.001% of phosphorus and the balance of iron;
laser texturing patterns such as: geometric patterns such as grooves, circles or diamonds;
(CoCrFeNiAl X Ta Y )N Z the thickness of the high-entropy alloy film is 4-6 mu m, (CoCrFeNiAl) X Ta Y )N Z Wherein X, Y, Z represents an atomic ratio of x=0.3 to 0.9, y=0.4 to 0.8, and z=0.3 to 0.5, and co, cr, fe, ni are equal to an atomic ratio of 1.
(CoCrFeNiAl X Ta Y )N Z In the high-entropy alloy film, the atomic ratio of Al, ta and N is respectively X=0.3-0.9, Y=0.4-0.8 and Z=0.3-0.5. If X is less than 0.3, the film hardness is low, the wear resistance is poor, and the wear resistance of the prepared metal steel ring is poor; if X>And 0.9, the film has poor ductility and toughness, and the prepared metal steel ring has poor fatigue strength. If Y < 0.4, no phase transition occurs, which results in low film hardness; if Y is more than 0.8, the film is liable to be cracked due to the large brittleness. If Z is less than 0.3, the number of metal nitride phases in the film is small, and the effect of improving the hardness and the wear resistance of the film is not obvious; if Z is more than 0.5, the number of metal nitride phases in the film is rapidly increased, so that defects such as columnar coarse crystals, air holes and the like are formed in the film, the film is easy to crack, the hardness and the elastic modulus of the film are reduced, and the wear resistance of the metal steel ring is deteriorated.
The invention relates to a preparation method of a metal steel ring in a steel belt component for a continuously variable transmission, which comprises the following steps:
(1) Preparing textured patterns on two surfaces of the strip-shaped general 18Ni series maraging steel by utilizing laser;
(2) Welding the strip-shaped general 18Ni series maraging steel treated in the step (1) into a metal steel ring;
(3) Depositing (CoCrFeNiAl) on the inner wall and the outer wall of the metal steel ring obtained in the step (2) by magnetron sputtering X Ta Y )N Z High entropy alloy film.
Further, the operation method of the step (1) is as follows:
polishing the surface of the strip-shaped general 18Ni series maraging steel by using silicon carbide sand paper sequentially according to the sequence of 320#, 600#, 1000#, 1500# and 2000#, placing the strip-shaped general 18Ni series maraging steel in acetone after polishing, performing ultrasonic vibration for 15min to wash out impurities on the surface, placing the strip-shaped general 18Ni series maraging steel in absolute ethyl alcohol, performing ultrasonic vibration for 15min to wash out residual acetone solution, and finally taking out and drying the strip-shaped general 18Ni series maraging steel; fixing the pretreated strip universal 18Ni series maraging steel on a laser processing working platform, opening a laser switch, and inputting laser technological parameters: laser power 60-80W, scanning speed 5-20mm/s, spot diameter 10-30 μm, pulse width 0.2-0.6ms, pulse frequency 15-30Hz, and scanning times 2-4 times; and processing the two surfaces of the steel material into texture patterns, wherein the texture sizes are 10-40 mu m in width, 5-20 mu m in depth and 100-300 mu m in interval between textures, the texture occupies 20-40% of the area, and taking out the steel material after the processing is finished, and closing a laser switch.
The invention uses laser to prepare textures with different shapes, which aims at: (1) in order to improve the bonding force between the substrate and the film; (2) increasing the wear resistance of the metal steel ring. The occupied areas of textures with different shapes are 20-40%, and the occupied areas refer to the proportion of the areas of the textures in the total area of the matrix. If the texture is less than 20% by area, the lubricant will have less storage and less wear resistance. If the texture is greater than 40% by area, too small a pit spacing causes a rapid increase in the surface roughness of the friction pair, thereby affecting the wear resistance of the metal steel ring.
In the step (2), welding modes such as laser welding and argon arc welding can be adopted. The specific operation method is as follows:
placing the strip-shaped general 18 Ni-series maraging steel with the texture morphology into acetone, performing ultrasonic vibration for 15min, washing off oxide on the surface, placing the strip-shaped general 18 Ni-series maraging steel into absolute ethyl alcohol, performing ultrasonic vibration for 15min, washing off residual acetone solution, and finally taking out and drying; opening a welding equipment switch, placing the pretreated steel on a welding fixture, and welding the rolled round edge after the steel is rounded, wherein welding parameters are set as follows: the welding power is 180-200W, the welding speed is 4-8mm/s, and the welding beam spot is 0.5-1.2mm; and after the welding is finished, closing the equipment switch, and taking out the metal steel ring.
