Detailed Description
The invention provides a metal wire material for laser cladding, which is mainly used for preparing a coating with corrosion resistance and high hardness requirement on the surface of a part. The metal wire material for laser cladding belongs to an iron-based stainless steel type material, and alloy elements for improving the toughness are added, so that the material has high corrosion resistance and high hardness and plasticity and toughness, and can be prepared into the metal wire material in a drawing mode.
The invention provides a metal wire material for laser cladding, and particularly belongs to a novel martensitic stainless steel material 1Cr14Ni2.5Cu2Nb formula, wherein the metal wire material for laser cladding comprises the following components in percentage by mass: c: 0.09-0.16%, Si: less than or equal to 1.0 percent, Mn: less than or equal to 1.0 percent, Cr: 13.50-16.50%, Ni: 1.50-3.50%, Cu: 1.30-2.25%, Nb: 0.10-0.20%, and the balance of Fe and other inevitable impurity elements.
The metal wire material for laser cladding comprises the following components in percentage by mass: c: 0.10-0.15%, Si: 0.35-0.75%, Mn: 0.30-0.60%, Cr: 14.00-15.50%, Ni: 1.80-2.9%, Cu: 1.50-2.00%, Nb: 0.10-0.15%, and the balance of Fe and other inevitable impurity elements.
According to the invention, the corrosion resistance of the material is ensured by reasonably blending the elements, the hardness of the material is improved, and the material has good plasticity and toughness, so that the wire material is convenient to prepare. Compared with the existing martensitic stainless steel, the stainless steel has excellent corrosion resistance and higher hardness, and the main alloy elements in the formula of the metal wire material have the following functions:
chromium (Cr): chromium is a main alloy element with a corrosion resistance effect, Cr can form a layer of compact oxide film on the surface of a part to protect the interior of the material, the content of the Cr element is controlled to be 13.50-16.50%, and a good corrosion resistance effect can be achieved. In order to satisfy the requirement of high hardness of the material, the content of Cr element is preferably controlled to 14.00-15.50%.
Nickel (Ni): the Ni element can improve the corrosion resistance and the toughness of the material, but the Ni element is an austenite forming element, the austenite structure of the material is increased when the Ni content is increased, and the hardness of the material is reduced, so that the content of the Ni element is controlled to be 1.50-3.50% in the invention, the more preferable content of the Ni element is 1.80-2.90%, and is generally more than 3% compared with the content of Ni in the prior art, the content of Ni is controlled to be within 3% in the most innovative way in the most practical embodiment of the invention, and the lower content of Ni can effectively reduce the austenite content in the structure and increase the strength of the material while keeping the corrosion resistance of the material by matching with other elements.
Copper (Cu): the Cu element can play a role in precipitation hardening in the stainless steel and can improve the corrosion resistance of the material, and the content of the Cu element in the stainless steel is controlled to be 1.30-2.25%, preferably 1.50-2.00%; compared with the prior art, the invention has the advantages that the Cu element content in the material is increased (about 2.0 percent of the Cu element is increased compared with the prior art) in an innovative manner, the precipitation hardening effect is realized, and the hardness of the material is increased.
Niobium (Nb): nb is a strong carbide forming element, can effectively improve the strength and the hardness of the material, has the function of precipitation hardening, and can stabilize the hardness of the material by proper Nb content. The content of Nb element is controlled to be 0.10-0.20%, and the preferable Nb content is 0.10-0.15%;
carbon (C): the C element is the main element for ensuring the hardness of the material, but for stainless steel, the content of the C element must be strictly controlled, and the C content is too high to cause the material to form Cr23C6The compound forms a Cr-poor area on the surface of the material, so that the corrosion resistance of the material is reduced, and the strength of the material is influenced by the low content of the C element, so that the hardness of the material is reduced, and the requirement of the invention cannot be met. Therefore, the content of the C element in the material in the formula of the invention is controlled to be 0.09-0.16%, and the content of the C element is preferably controlled to be 0.10-0.15%.
In addition, the formula material of the invention does not add slagging elements such as Si, B and the like, thereby reducing the slag inclusion risk of the material and improving the plasticity and toughness of the material. Compared with the prior art, the novel wire drawing material does not contain Mo element, so that the improvement of the plasticity and toughness of the material is facilitated, the wire drawing material is easier to prepare by drawing, and the novel wire drawing material is a great improvement compared with the prior art.
The metal wire material for laser cladding is prepared by the following steps:
step one, weighing all the components according to the mass ratio of all the components in the metal wire material for laser cladding, and uniformly mixing the weighed components to form an original material mixture;
secondly, putting the original material mixture obtained in the first step into a smelting furnace, and smelting at high temperature under the protection of inert gas to obtain liquid molten alloy;
step three, casting the liquid molten alloy obtained in the step two into a continuous casting square billet, and rolling the square billet into a wire rod with the diameter phi of 5.0 mm-phi of 8.0mm through hot rolling;
