通过化学镀在42Cr Mo钢上沉积Ni-P-SiCP复合镀层。分析了在不同热处理温度下加工的不同SiCP浓度Ni-P-SiCP复合镀层的表面形貌和相结构。研究了Ni-P-SiCP复合镀层的显微硬度、耐腐蚀性和耐磨性。结果表明，Ni-P-SiCP复合镀层呈现花椰菜状形貌。增加SiCP浓度可以减小胞状物的尺寸。显微硬度和耐腐蚀性随着SiCP浓度的增加而先增加后降低。当SiCP浓度为5 g/L时，最大显微硬度和腐蚀电位分别为7379 MPa和-0.363 V。Ni-P-SiCP复合镀层呈现非晶态结构，漫散衍射峰的宽度随着SiCP浓度的增加而变窄。这表明SiCP抑制了P的沉积，促进了微晶转变。在350℃下热处理后，Ni-P-SiCP复合镀层结晶，导致Ni3P相沉淀。在400℃下热处理1 h可使结构最大化。镀层中Ni3P析出强化相和SiCP弥散强化相的协同作用，促进了胞状组织的致密化，从而获得了最佳的显微硬度（13 828MPa）、最佳的耐腐蚀性（-0.277 V）和优异的耐磨性。磨损机制以微切削磨料磨损为主，伴有轻微的粘着磨损和氧化磨损。

BACKgROUND： Peripheral venous pressure （PVP） has been shown to correlate with central venous pressure （CVP） in a number of reports. Few studies, however, have explored the relationship between tissue pressure （TP） and PVP/CVP correlation. METHODS： PVP and CVP were simultaneously recorded in a bench-top model of the venous circulation of the upper limb and in a single human volunteer after undergoing graded manipulation of tissue pressure surrounding the intervening venous conduit. Measures of correlation were determined below and above a point wherein absolute CVP exceeded TP. RESULTS： greater correlation was observed between PVP and CVP when CVP exceeded TP in both models. Linear regression slope was 0.975 （95% CI： 0.959-0.990）; r2 0.998 above tissue pressure 10 cmH20 vs. 0.393 （95% CI： 0.360-0.426）; and r2 0.972 below 10 cmH2O at a flow rate of 2000 mL/h in the in vitro model. Linear regression slope was 0.839 （95% CI： 0.754-0.925）; r2 0.933 above tissue pressure 10 mmHg vs. slope 0.238 （95% CI： -0.052-0.528）; and r20.276 in the en vivo model. CONCLUSIONS： PVP more accurately reflects CVP when absolute CVP values exceed tissue pressure.
