Description
技术领域technical field
本发明涉及一种钎涂材料，尤其是涉及一种层状复合钎涂材料，本发明还涉及该钎涂材料的制备方法。The invention relates to a brazing coating material, in particular to a layered composite brazing coating material, and also relates to a preparation method of the brazing coating material.
背景技术Background technique
在机械领域，某些工件局部表面往往要求具有较高的耐磨性和抗腐蚀性。如果将整体工件都用耐磨合金或抗腐蚀材料制造，不但成本较高，而且在整体力学性能等方面往往又不能满足要求。合理的解决方法通常是采用表面处理技术，即在工件的工作面上涂覆一层耐磨或耐蚀的金属或合金。就耐磨层而言，常用的方法有物理气相沉积法(PVD)、化学气相沉积法(CVD)、热喷涂法、堆焊法及钎涂法。物理气相沉法和化学气相沉积法只能取得很薄的涂层；等离子喷涂和火焰喷涂一般只能达到约1mm厚的涂层；表面堆焊法的加热温度较高，容易产生热应力，焊层一般较薄；钎涂法则不同，用钎涂法可以得到厚度范围比较大的涂层（从最薄的0.05mm到比较厚的4mm）。另外，钎涂层与母材系冶金结合，结合强度比热喷涂的机械结合要高得多；同时钎涂比堆焊时的加热温度低，热应力和母材性能的变化较小；而且钎涂层表面光滑，施工精度高，经过少量的加工即可达到要求的精度。In the field of machinery, the local surface of some workpieces is often required to have high wear resistance and corrosion resistance. If the whole workpiece is made of wear-resistant alloys or corrosion-resistant materials, not only the cost is high, but also the overall mechanical properties and other aspects often cannot meet the requirements. A reasonable solution is usually to use surface treatment technology, that is, to coat a layer of wear-resistant or corrosion-resistant metal or alloy on the working surface of the workpiece. As far as the wear-resistant layer is concerned, the commonly used methods are physical vapor deposition (PVD), chemical vapor deposition (CVD), thermal spraying, surfacing and brazing. Physical vapor deposition and chemical vapor deposition can only obtain very thin coatings; plasma spraying and flame spraying generally can only achieve about 1mm thick coatings; The layer is generally thin; the braze coating method is different, and the braze coating method can be used to obtain a coating with a relatively large thickness range (from the thinnest 0.05mm to the thickest 4mm). In addition, the brazing coating is metallurgically bonded to the base metal, and the bonding strength is much higher than the mechanical bonding of thermal spraying; at the same time, the heating temperature of the brazing coating is lower than that of surfacing, and the thermal stress and the properties of the base metal have little change; and the brazing coating The surface of the coating is smooth and the construction precision is high, and the required precision can be achieved after a small amount of processing.
钎涂法中所用的钎涂材料由两部分组成：一部分是钎料合金，它的熔化温度较低，通称低熔点组分；另一部分是熔点高的硬质合金，通称高熔点组分。传统的钎涂材料通常是将粉状钎料、硬质合金颗粒、粘接剂、有机物等制备成悬浮的浆料状钎涂材料或片状钎涂材料，然后涂覆或粘结在工件表面，为防止母材、粉状钎料的氧化及促进钎料在硬质合金颗粒、母材表面的润湿铺展，钎涂过程中往往需要不断添加钎剂，工作效率低且容易造成钎剂的大量浪费，成本较高。The braze coating material used in the braze coating method consists of two parts: one part is a brazing alloy, which has a lower melting temperature and is commonly known as a low melting point component; the other part is a hard alloy with a high melting point, commonly known as a high melting point component. Traditional brazing materials are usually prepared by preparing powdered brazing material, cemented carbide particles, adhesives, organic matter, etc. into suspended slurry brazing materials or sheet brazing materials, and then coated or bonded on the surface of the workpiece In order to prevent the oxidation of the base metal and powdered solder and promote the wetting and spreading of the solder on the surface of the cemented carbide particles and the base metal, it is often necessary to continuously add flux during the brazing coating process, which is low in work efficiency and easily causes flux loss. A lot of waste and high cost.
