The objective of the present work was to determine the influence of the neutral salt spray corrosion on the wear resistance of HVOF sprayed NiCr-Cr3C2 coating with intermediate layer. Ni-Zn-Al2O3 coatings as interlayers were prepared by low pressure cold spray（LPCS） between NiCr-Cr3C2 cermet coatings to form a sandwich structure to enhance the corrosion resistance properties. The tribological properties were examined using the UMT-3 fricition and wear tester by line-contact reciprocating sliding under dry and salt spray one week corrosion. The morphology, element distribution, and phase compositions of the coating and worn sufaces were analyzed by using scanning electron microscopy, energy dispersive spectrometry, and X-ray diffraction respectively. The corrosion behavior of the coating was studied by the open-circuit potential, the electrochemical impedance spectroscopy, potentiodynamic polarization, and salt spray corrosion methods. It is found that the sandwich structured coating has better corrosion resistance than the single layer coating. The results show that under dry wear conditions, the wear mechanism is abrasive and adhesive wear, whereas under salt spray corrosion conditions it becomes corrosion wear. The friction coefficient of the sandwich structured coating after salt spray corrosion is slightly lower than the dry friction coefficient, but the weight of the wear loss is lower than that under dry condition.

利用超音速等离子喷涂(SPS)技术制备了陶瓷相增强的NiCr-Cr_3C_2涂层,采用线接触往复滑动方式进行摩擦磨损实验,测定了NiCr-Cr_3C_2涂层/Q235碳钢摩擦副在盐雾腐蚀前后涂层的摩擦系数和磨损量,此外,还采用SEM、EDS等技术观察分析了涂层表面的形貌和微区元素分布,探讨了盐雾腐蚀环境对涂层摩擦磨损性能的影响。结果表明:NiCr-Cr_3C_2涂层的磨损机制主要为磨粒磨损和氧化磨损,而盐雾腐蚀后的磨损机制为粘着磨损、磨粒磨损和腐蚀磨损。盐雾腐蚀后涂层的摩擦系数比盐雾腐蚀前的摩擦系数降低了1/5;不过,盐雾腐蚀后涂层的磨损失重量是盐雾腐蚀前磨损失重量的5倍左右,说明盐雾腐蚀环境加速了其摩擦学性能的恶化,涂层的耐蚀性有待进一步提高。

为了缩短冷喷涂设备的研发周期和降低设计的复杂性,采用数值模拟技术分析冷喷涂加热过程中空气的换热特性.通过计算流体力学(CFD)软件Star-CCM+,分析了输入功率、加热器电阻元件结构和气体流量等因素对气体出口温度的影响.结果表明:管内气体的速度不会发生较大的变化,整个加热器可以达到一个稳定的温度场分布,加热管的温度和气体最高温度间存在较大的温度差.合适的结构设计可提升换热效率、降低气体和螺旋管间的温度差、提高加热器的工作温度.将螺旋管的中心距增大,可以提升气体的湍流度,提升换热效率;螺旋管间距缩小才能增加出口的温度.螺旋管的直径为8～12 mm时为宜,过大过小都会导致换热效率降低.

高强钢10CrNi3MoV焊接接头在海水服役过程中容易发生腐蚀。采用三维视频图像原位采集系统分析10CrNi3MoV焊接接头的各区域分布,采用扫描开尔文探针确定了焊接接头的易腐蚀区域,采用电化学综合测试系统进行了焊接接头的电化学测试。结果表明,热影响区的面积小,在海水浸泡中热影响区表面伏打电位低,作为阳极优先腐蚀。焊接接头在海水浸泡中的腐蚀主要以点蚀为主。热影响区的腐蚀电流密度最大,阻抗谱中电荷转移电阻最小,腐蚀速率最快,腐蚀情况最严重,而母材与焊缝电荷转移电阻相差不大,两者腐蚀速率相当。本研究可为改进高强钢焊接接头的工艺参数提供一定的理论指导。
