c=63.8 N),這可能歸因于最高的材料硬度(H)/彈性模量(E)和H3/E2數(shù)值比(分別為0.083和0.138)。Cr層越厚,多層Cr/CrN厚涂層的塑性和摩擦學(xué)性能越好。干摩擦試驗(yàn)表明,與單層CrN相比,Cr/CrN多層涂層的平均摩擦系數(shù)和比磨損率分別最高降低了24%和94%。隨著Cr層變厚,磨損機(jī)理從表面疲勞磨損轉(zhuǎn)變?yōu)槟チ夏p,這種現(xiàn)象可歸因于硬度和塑性的協(xié)調(diào)變化。;The thick Cr/CrN multilayer coatings with different modulation ratios (1:2, 1:3, 1:5) were deposited on the A100 steel substrate at room temperature by multi-arc ion plating (MAIP). The chamber temperature gradually rose to 160~170 °C during deposition. The modulation structures are designed to optimize the adhesion strength and the mechanical properties. The Cr/CrN multilayer coating with modulation ratio of 1:2 exhibits the highest adhesive strength (Lc=63.8 N), which may be attributed to the highest hardness (H)/elastic modules (E) and H3/E2 values of 0.083 and 0.138, respectively. The thicker the Cr layer, the better the plasticity and tribological properties. The dry friction test shows that the mean coefficient of friction and the specific wear rate of Cr/CrN multilayer coating are decreased by 24% and 94% at most, respectively, compared with those of the single-layer CrN coating. As the Cr layer becomes thick, the wear mechanism is transformed from surface fatigue wear to abrasive wear, which may be attributed to the coordinate changes of hardness and plasticity."/>
