具体实施方式 Detailed ways
为了使得本领域的技术人员能够更加清楚地了解本发明的技术方案，下面进行详细说明。In order to enable those skilled in the art to understand the technical solutions of the present invention more clearly, detailed descriptions are given below.
技术方案1.Technical solution 1.
一种激光熔覆用合金粉末，包括：An alloy powder for laser cladding, comprising:
0.01～0.15％的C，0.01～0.15% C,
0.5％～1.0％的Si，0.5%～1.0% Si,
0.4％～0.8％的Mn，0.4%～0.8% Mn,
17.5％～19.5％的Cr，17.5%～19.5% Cr,
21％～25％的Ni，21%～25% Ni,
余量的Fe和不可避免的杂质；The balance of Fe and unavoidable impurities;
其中，以上各种元素的含量为重量百分比含量。Wherein, the content of the above various elements is the weight percentage content.
首先需要说明的是，本发明的激光熔覆用合金粉末的各种元素的种类以及含量是专门针对于激光熔覆而开发的合金粉末，虽然在现有技术中对各种元素的作用有各种说明，但是本发明的激光熔覆用合金粉末的各种元素和含量配合良好，生产出的具有熔覆层的立柱，不容易产生裂纹，而且，表面硬度、使用寿命、熔覆层与金属基体的结合强度、耐盐雾性能这四项的综合性能良好。只要在本发明的元素种类和配合比例的范围内，就能够得到综合性能好的具有熔覆层的立柱。本发明的激光熔覆用合金粉末不能与简单合金粉末比较，因为激光熔覆技术中，激光的加工面积小而能量大，并且时间短，以上的各种合金粉末在熔化之后，融化体中的各种元素均匀分布，并且在成型之后还需要加工去除一部分熔覆层上层的物质，所以为了得到综合性能良好的熔覆层等，发明人经过多次试验以及潜心专研，终于获得了本发明的以上的激光熔覆用合金粉末。First of all, it needs to be explained that the types and contents of various elements of the alloy powder for laser cladding of the present invention are alloy powders specially developed for laser cladding, although there are different effects on various elements in the prior art. However, the various elements and contents of the alloy powder for laser cladding of the present invention are well coordinated, and the column with the cladding layer produced is not prone to cracks, and the surface hardness, service life, cladding layer and metal The comprehensive performance of the four items of matrix bonding strength and salt spray resistance is good. As long as the types of elements and the mixing ratio of the present invention are within the range, a column with a cladding layer with good comprehensive performance can be obtained. The alloy powder for laser cladding of the present invention cannot be compared with simple alloy powder, because in the laser cladding technology, the processing area of the laser is small and the energy is large, and the time is short. Various elements are evenly distributed, and part of the upper layer of the cladding layer needs to be processed and removed after molding. Therefore, in order to obtain a cladding layer with good comprehensive performance, etc., the inventor finally obtained the present invention after many experiments and dedicated research. The above alloy powders for laser cladding.
然后，对本发明的技术方案中的各种元素和含量进行说明。Next, various elements and contents in the technical solutions of the present invention will be described.
钢中的含碳(C)量增加，钢的强度和耐磨性增强，但是当钢的含碳量超过0.20％时，钢的耐腐蚀性变差，因此用于立柱熔覆的低合金结构钢，含碳量一般不超过0.20％。而本发明的激光熔覆用合金粉末的含碳量在0.15％以下，在熔覆以后，完全可以满足这些性能。The amount of carbon (C) in the steel increases, and the strength and wear resistance of the steel increase, but when the carbon content of the steel exceeds 0.20%, the corrosion resistance of the steel becomes poor, so the low alloy structure used for column cladding For steel, the carbon content generally does not exceed 0.20%. However, the carbon content of the alloy powder for laser cladding of the present invention is below 0.15%, which can fully satisfy these properties after cladding.
硅(Si)在激光熔覆过程中起到良好的脱氧造渣作用，另外，硅能够提高熔覆合金钢的硬度和强度。但是，含硅量超过1.5％时，将显著降低钢的塑性和韧性。在本发明的技术方案中，激光熔覆用合金粉末中的硅含量为0.5～1.0％，能够较好地发挥其上述的各项性能。Silicon (Si) plays a good role in deoxidation and slagging during laser cladding. In addition, silicon can improve the hardness and strength of cladding alloy steel. However, when the silicon content exceeds 1.5%, the plasticity and toughness of steel will be significantly reduced. In the technical solution of the present invention, the silicon content in the alloy powder for laser cladding is 0.5-1.0%, which can better exert its above-mentioned various properties.
锰(Mn)是良好的脱氧剂和脱硫剂。合金粉末中含有一定量的锰，它能消除或减弱由于硫所引起的钢的热脆性，从而改善钢的热加工性能。在本发明的技术方案中，锰的含量为0.4～0.8％，可以起到脱氧和脱硫的作用。Manganese (Mn) is a good deoxidizer and desulfurizer. The alloy powder contains a certain amount of manganese, which can eliminate or weaken the hot embrittlement of steel caused by sulfur, thereby improving the hot workability of steel. In the technical solution of the present invention, the content of manganese is 0.4-0.8%, which can play the role of deoxidation and desulfurization.
铬(Cr)能够使立柱用激光熔覆合金钢具有良好的耐腐蚀性能。另外铬能增加钢的淬透性并且有二次硬化的作用，可以提高钢的硬度和耐磨性。Chromium (Cr) can make the laser cladding alloy steel for columns have good corrosion resistance. In addition, chromium can increase the hardenability of steel and has the effect of secondary hardening, which can improve the hardness and wear resistance of steel.
镍(Ni)元素的加入，能够提高立柱用激光熔覆合金钢的耐腐蚀性能和塑韧性。The addition of nickel (Ni) element can improve the corrosion resistance and ductility of the laser cladding alloy steel for columns.
技术方案7Technical scheme 7
本发明的激光熔覆用合金粉末，优选使用粉末形态。而粉末形态的组合物的生产方法可以有两种，一种是水雾化的生产方法，另一种是气雾化的生产方法。通过这两种方法生产得到的粉末即为水雾化型粉末和气雾化型粉末。本发明对于水雾化的生产方法和气雾化的生产方法并没有特殊的要求，只要使用现有技术中的生产方法即可。The alloy powder for laser cladding of the present invention is preferably used in a powder form. There are two production methods for the composition in powder form, one is the production method of water atomization, and the other is the production method of gas atomization. The powders produced by these two methods are water atomized powder and gas atomized powder. The present invention has no special requirements on the production method of water atomization and gas atomization, as long as the production method in the prior art is used.
技术方案8～12Technical scheme 8～12
在合金粉末中，加入少量的Mo、Ti、V、Nb和Cu等元素，可以提高熔覆合金层的耐腐蚀性能。In the alloy powder, adding a small amount of elements such as Mo, Ti, V, Nb and Cu can improve the corrosion resistance of the cladding alloy layer.
