Comparison of advantages between high-speed laser cladding and ordinary laser cladding:

 

Effectiveness:

When the effective coating of mechanical parts is 0.5mm, the high-speed laser only needs to cladding 0.8mm thick coating, and the efficiency is 0.8~1.2㎡/h; while conventional laser cladding requires 1.3~1.5mm thick coating , The efficiency is 0.3~0.6㎡/h, and the efficiency of high-speed laser cladding is 2~3 times that of ordinary laser cladding.

Powder consumption:

High-speed laser cladding 0.8mm thick coating, the powder consumption is 5.8~6.3kg/㎡, while the ordinary laser cladding 1.5mm thick coating, the powder consumption is 10-11kg/㎡, which will eventually remain on the workpiece The effective coating is 0.5mm, which is about half of the powder cost of high-speed laser cladding.

Machine plus margin:

The coating processing allowance after high-speed laser cladding is only 0.2~0.3mm on one side to finish the finished product. The coating processing allowance after ordinary laser cladding needs 0.7~1mm on one side to process the finished product, which is not only inefficient, but also Powder material is wasted.

Calories:

High-speed laser cladding because of the high speed of the workpiece, the feed line speed, and the more concentrated energy density, the heat input to the workpiece is very small. When cladding special workpieces such as slender rods and thin-walled parts, the heat is low and the deformation is very small. In ordinary laser cladding, because the beam mode is flat-top light, the spot is elongated, the power is large during cladding, the speed is low, the walking feed speed is slow, and the stay on the workpiece is long, and the heat input is 3 of the high-speed laser. ~5 times above, resulting in cladding of thin-walled parts, large deformation of the slender rod, and even scrap after cladding.

Application area:

High-speed laser cladding can be processed according to different coating requirements, and can meet Fe, Ni, Co, 316L, Ni60Wc, H13, Inco718, 625, tool steel alloys, die steel alloys, various corrosion-resistant and wear-resistant alloy materials, high Laser cladding of melting point alloys can also cladding low melting point alloys such as copper and aluminum.

Vibrating screen
The vibrating screen uses a vertical vibrating motor as the excitation source. The upper and lower ends of the vibration motor are equipped with eccentric heavy objects, which transform the rotational motion of the vibratory motor into a horizontal, vertical and tilted three-dimensional motion, which is then transmitted to the screen surface. Adjusting the phase angle of the upper and lower ends can change the movement trajectory of the material on the screen surface.

Supersonic spraying equipment
The supersonic flame is a high-temperature, high-speed combustion flame flow produced by burning propane, propylene and other hydrocarbon gas or hydrogen gas and high-pressure oxygen in the combustion chamber or in a special nozzle. The combustion flame flow speed can reach Mach 5 (1500m/ s) above. Usually called HVOF (High-velocityoxygen-fuel). The powder is fed into the flame axially, and the sprayed particles can be heated to a molten or semi-melted state, and accelerated to a speed as high as 300-500m/s, or even higher, so as to obtain a high-quality coating with high bonding strength and compactness. . The supersonic flame speed is very high, but the temperature is relatively low. For WC-Co cemented carbide, it can effectively inhibit the decomposition of WC during the spraying process. The coating not only has high bonding strength, but is also dense and has excellent wear resistance. Its wear resistance greatly exceeds that of plasma sprayed coatings, which are equivalent to explosive sprayed coatings, and also exceed spot plating hard chromium coatings and molten spray coatings. It is extremely widely used.

Cold spray equipment
Supersonic cold spraying, also known as low pressure cold spraying, is a new type of metal spraying process. It is different from traditional cold spraying. It does not need to melt the sprayed metal particles. The temperature of the sprayed substrate surface generally does not exceed 150°C. The principle of supersonic cold spray technology is to use compressed gas to generate supersonic airflow through a zoom-type Lava tube, and send the powder into the supersonic airflow along the axial direction to form a gas-solid two-phase flow, which will hit the substrate in a completely solid state after acceleration , Large plastic deformation occurs and deposits on the surface of the substrate to form a coating.

Plasma cladding equipment
Plasma cladding technology is a new material surface modification technology that uses plasma beam as a heat source to obtain excellent wear resistance, corrosion resistance, heat resistance, and impact resistance on the metal surface. This technology melts the alloy powder synchronously sent to the surface of the workpiece under the irradiation of the high-energy plasma beam, and simultaneously melts the shallow layer of the workpiece surface, forming an alloy molten pool on the surface of the workpiece; after the high-energy beam is removed, the workpiece Under the action of its own rapid heat conduction and the radiation heat transfer of the air around the workpiece, the alloy molten pool is rapidly solidified to form a high-quality coating with uniform composition, compactness, fine and uniform structure, no microscopic pores and cracks, and a good metallurgical bond with the workpiece . Plasma cladding is a rapid non-equilibrium solidification process, which has multiple strengthening effects such as supersaturated solid-liquid strengthening, dispersion strengthening and precipitation strengthening. Compared with laser cladding and electron beam cladding, plasma cladding is a new surface modification technology with high quality, high efficiency and low cost.
