| 中文摘要: |
| 目的 解决某产品箱体等复杂构件耐磨、减摩、抗烧蚀、残渣难清理引起的腐蚀等问题。方法 开展协合涂层工艺研究及应用试验验证，通过扫描电镜观察(SEM)、成分能谱分析(EDS)及厚度、硬度、附着强度(热震法)、中性盐雾试验、球盘式摩擦磨损试验等对涂层进行性能测试。结果 该涂层厚度均匀可控，与基体结合力强，在300~500 ℃共5个热震循环后，结合力未受影响。硬度高，超过800HV1.0，与铬镀层相当。耐磨性及耐腐蚀性好，6 000次摩擦磨损试验后，无明显磨痕，中性盐雾1 200 h为评级为8级。通过涂层制备工艺对高频淬火部位性能影响研究分析，摸清了涂层制备对高频淬火部位的影响规律。通过箱体等复杂零件试生产，解决了涂层“发花”及“气馕袋”等制备问题。结论 经多轮产品试验验证，该涂层完全能满足产品使用要求。 |

| The work aims to tackle challenging requirements of complex structure such as a housing part, including wear resistance, abrasion reduction, anti-ablation, and corrosion resistance against persistent stain. Process and engineering application of the synergistic coating were conducted. Properties of the coating were characterized with SEM/EDS, thickness test, hardness test, adhesion test, neutral salt spray test and ball-disc wear test. The coating exhibited evenly distributed thickness, outstanding adhesion with the substrate after 5 thermal shock cycles at 300~500 ℃. Its hardness was as high as 800HV1.0, which was similar to that of the chromium plating. It had good wear resistance. There was no obvious scratch after 6 000 time wear tests. It had good corrosion resistance with a level 8 rating after 1 200 h of neutral salt spray test. Through the study and analysis on the effect of coating preparation technology on the properties of high-frequency quenching parts, the affecting law of coating preparation on high-frequency quenching parts was made clear. Obstacles encountered in manufacturing the coating on the housing part, such as “defective” and “gas-pocketed” areas were resolved. For the housing part, synergistic coating provides a performance that well satisfies the requirement, which is verified by extended product test. |
