Description
Technical Field
The invention belongs to the technical field of surface treatment, and particularly relates to a corrosion-resistant and abrasion-resistant coating and a cold spraying preparation method thereof.
Background
In the fields of electronic and electrical appliances, mechanical equipment, transportation, aerospace, weaponry and the like, a large number of metal parts are subjected to tests in severe environments such as corrosion, abrasion and the like in the service process until the metal parts are finally scrapped due to corrosion and abrasion. In order to improve the service life of these metal parts, it is usually necessary to perform appropriate surface treatment on these metal parts before use to improve the corrosion resistance and wear resistance of the metal parts.
There are many methods for treating the surface of metal parts, such as chemical conversion coating, anodic oxidation, electroplating, thermal spraying, laser modification, etc. Chemical conversion coatings are widely used as a paint primer, but the chemical conversion coatings only slow down the corrosion rate and are not effective in preventing corrosion. Anodic oxidation can produce a certain wear-resistant and corrosion-resistant oxide film, but the oxide film is brittle and porous, and it is difficult to obtain a uniform oxide film. The plating solution of the electroplating method often contains heavy metal ions, which causes certain pollution to the environment. The metal coating is deposited on the surface by thermal spraying, and the surface of the metal part can generate strong reaction in the thermal spraying process, so that the surface is oxidized, and an oxidation film with poor corrosion resistance is generated. The metal parts are easy to be oxidized, evaporated and generate thermal stress during laser modification treatment.
The cold spraying technology is a novel spraying technology which takes compressed gas as an accelerating medium, and drives spraying powder to collide with metal parts at a high speed in the spraying process based on the gas dynamics principle, so that the powder is subjected to plastic deformation deposition to form a coating. Compared with other coating preparation technologies, the equipment and the device are convenient to operate and use, the powder particles are low in heating temperature and do not need to be heated to a molten state in the spraying process, the thermal stress is not generated, the bonding strength is high, and the influence on the metal part matrix is basically avoided. The lower process temperature (lower than the melting point of the spraying material) can avoid the oxidation of metal particles and the growth of crystal grains in the spraying process. Compared with an electrochemical method and the like, cold spraying is an environment-friendly green coating preparation process. Unfortunately, the cold spray coating is mainly made of pure aluminum, and although pure aluminum has better corrosion resistance, the strength and hardness of the cold spray coating are low, so that the cold spray coating is still difficult to adapt to the surface protection needs of metal parts under the severe environments of corrosion and abrasion, and the application of the cold spray technology is greatly limited. Thus, there is still a need for improvement and development of the existing cold spray coating and its cold spray method.

Detailed Description
The corrosion-resistant and abrasion-resistant coating is prepared by a cold spraying method and comprises the following components in percentage by mass: 0.25 to 0.35 percent of Cu, 0.26 to 0.28 percent of Mg, 0.19 to 0.22 percent of Si, 0.35 to 0.4 percent of Ni,0.05 to 0.15 percent of Co, 0.15 to 0.25 percent of Sn, 0.05 to 0.15 percent of Cr, 0.3 to 0.45 percent of Zr, 0.06 to 0.09 percent of B, the balance of Al and inevitable impurities, the content of single impurity is less than or equal to 0.01 percent, and the total content is less than or equal to 0.05 percent.
Wherein, the main function of Cu, mg and Si is to enhance the hardness of the coating, and the elements can form CuAl in addition to the solid solution strengthening effect in the coating 2 Strengthening phases, mg and Si forming Mg 2 Si strengthening phase, strengthening coatingThe hardness of the layer. The higher the content of Cu, mg and Si, the higher the hardness of the coating, but the too high the content of Cu, mg and Si, the coating becomes brittle easily because it is too hard. After extensive experimental study on the composition of the coating, the inventors found that when the Cu content is less than 0.25%, the Mg content is less than 0.26%, or the Si content is less than 0.19%, the hardness of the coating does not reach 90HRB. When the Cu content is more than 0.35%, the Mg content is more than 0.28%, or the Si content is more than 0.22%, the hardness of the coating exceeds 110HRB, and the coating becomes brittle due to excessively high hardness. Only when the Cu content is 0.25-0.35%, the Mg content is 0.26-0.28%, and the Si content is 0.19-0.22%, the coating hardness is 90-110 HRB.
The Ni, co and Cr have high melting point and good high-temperature stability, can further enhance the hardness of the coating, and mainly has the functions of improving the bonding strength of the coating and a metal part matrix and simultaneously improving the high-temperature stability and the ablation resistance of the coating. The inventor discovers through a great amount of experimental researches on the component composition of the coating that the effect of compositely adding three elements of Ni, co and Cr is better than the effect of singly adding one or two elements under the condition of the same total adding amount, when 0.35-0.4% of Ni, 0.05-0.15% of Co and 0.05-0.15% of Cr are compositely added, the bonding strength of the coating and a metal part substrate can be obviously improved, and simultaneously, the high-temperature stability and the ablation resistance of the coating are improved, thereby being beneficial to improving the abrasion resistance and the corrosion resistance of the coating.
Sn is a weak metal with softness and strong ductility, has high density and high corrosion resistance, and the inventor finds that the corrosion resistance of the coating can be obviously improved by adding 0.15-0.25% of Sn into the coating through a large amount of experimental researches. In addition, because the texture of Sn is soft, a small amount of Sn is added into the coating, so that the coating can play a role in lubricating in the abrasion process, and the abrasion resistance of the coating is improved.
Zr and B are added into the coating in the form of AlZr5B1 alloy, the AlZr5B1 alloy is obtained by reacting a mixture of sodium fluorozirconate and sodium fluoroborate with aluminum liquid, and the interior of the AlZr5B1 alloy contains a large amount of ZrB with the grain diameter of less than 1 micron 2 Particles, zrB 2 High particle hardness, high melting point and good stabilityAdding 6-9% of AlZr5B1 alloy and a large amount of ZrB in the smelting process 2 The particles are finally dispersed in the coating, and play a role in supporting the salient points in the abrasion process of the coating, thereby obviously improving the abrasion resistance of the coating.
