摘要

为研究高频聚能爆炸喷涂技术在制备WC-12Co耐磨涂层方面的应用，并优化喷涂工艺参数，以获得低孔隙率、高结合强度的涂层。采用高频聚能爆炸喷涂设备在Q235钢基材上制备WC-12Co涂层，并通过正交试验研究氧燃比、填枪比和送粉速度等工艺参数对涂层孔隙率和显微硬度的影响。正交试验结果表明，氧燃比对涂层孔隙率和显微硬度的影响最为显著，其次是送粉速度，填枪比的影响最小。最佳工艺参数为氧燃比5.1，填枪比0.6，送粉速度18.6 g/min，在该工艺条件下制备的涂层孔隙率仅为0.24%，显微硬度达到887 HV0.3。涂层结合强度测试结果显示，结合强度超过76.3 MPa，远高于普通爆炸喷涂技术制备的涂层。高频聚能爆炸喷涂技术制备的WC-12Co涂层具有低孔隙率、高结合强度、高硬度和优异的综合性能，具有广阔的工程应用价值。

Abstract

The aim is to study the application of high-frequency detonation spray technology in the preparation of WC-12Co wear-resistant coatings

and to optimize the spray process parameters to obtain coatings with low porosity and high bonding strength. WC-12Co coatings were prepared on Q235 steel substrate using high-frequency detonation spray equipment

and the effects of process parameters such as oxygen-fuel ratio

filling gun ratio

and powder feeding speed on the porosity and microhardness of the coating were studied through orthogonal experiments. The results of the orthogonal experiment show that the oxygen-fuel ratio has the most significant effect on the porosity and microhardness of the coating

followed by the powder feeding speed

and the filling gun ratio has the least effect. The optimal process parameters are an oxygen-fuel ratio of 5.1

a filling gun ratio of 0.6

and a powder feeding speed of 18.6 g/min. Under these process conditions

the porosity of the prepared coating is only 0.24%

and the microhardness reaches 887 HV0.3. The results of the coating bonding strength test show that the bonding strength exceeds 76.3 MPa

which is much higher than that of coatings prepared by ordinary detonation spray technology. The WC-12Co coating prepared by high-frequency detonation spray technology has low porosity

high bonding strength

high hardness

and excellent comprehensive performance

and has broad engineering application value.
