II abradability, scratches, the surface, colorfast, water, oil, and very welcome, particularly yanhe confidein, in speeds up to 300-500 package/minute high speeds, the cigarette brand are subjected to enormous mechanical loads, so business card printing and membership card making products not only need polishing, but also to have a very strong resistance to abrasion, and water is not only fulfill this requirement, and both the gravure printing or offsctdruckereien no cigarette packets are retained wash after wash.

耐磨性强，抗划痕，被印物表面耐磨、不掉色、斥水、斥油，深受用户的欢迎和信赖，尤其是烟盒，在速度高达300-500包/分钟的高速运转中，烟标要承受很大的机械负荷，为此制卡和会员卡制作品不仅需要上光，而且要有很强的耐磨性，水性上光油不仅能完全满足这一要求，而且无论是凹印还是胶印均无发现烟包掉色的现象。

The hardness and wear resistance increase with increasing TiB2 content. Adding about 1.5%Mg in melt restrains the conglobation of the TiB2 particles, which makes the size of TiB2 particle decrease and the distribution of TiB2 particle is more homogeneous. The strengthening effect of TiB2 particles is enhanced and the hardness and wear resistance of composites are obviously improved. The excess Mg decreases the refinement effect of TiB2 particles, but the hardness and wear resistance are improved continuously.

结果表明：反应生成的TiB2颗粒平均尺寸约为0.5 μm，材料的硬度和耐磨性随着TiB2含量的增加而提高；添加1.5%Mg元素可明显细化TiB2颗粒，且使其分布更加均匀，增强TiB2颗粒的弥散强化和细晶强化效果，复合材料的硬度和耐磨性显著改善；过量的Mg元素(3%)会造成TiB2颗粒细化效果的下降，但其硬度和耐磨性能继续得到改善。

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。

The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.

表明：(1)激光熔覆合金层是由过饱和的γ基体相和复杂的六方M_7C_3碳化物相所组成(2)在其他参数不变的情况下，随激光扫描速度的提高，γ基体相过饱和度增大，而析出的碳化物含量减少，因而合金层的硬度升高，耐磨性有所下降；而降低激光的扫描速度，碳化物M_7C_3析出增加，有利于提高合金层的耐磨性、因此碳化物M_7C_3析出量是提高耐磨性的主要因素，而增加基体相γ的过饱和度则是硬度提高的主要因素
