  1. There are pitting erosion and fatigue effect on the working surface of the rolling hearing because of the chemical and physical reasons, which may cause the advanced failure in bearings

    針對軸承早期失效點腐蝕及疲勞，從材料本身的質量及軸承的工作條件，分析了軸承點腐蝕及疲勞失效發生及發展的原理。
  2. The result shows that under the effect of repeated impact load, the stress wave produces reflection in the metallurgical junction plane between coating and basal body, and forms stretch wave causing longitudinal split and angle split of coat ; the microcosmic spot pitting and deep layered peeling off occur in coating surface due to stress concentration ; the energy accumulation of impact loading causes rigidity variation and plastic deformation

    結果表明：在多沖載荷作用下，應力波在塗層和基體的冶金接合面發生反射，形成拉伸波造成塗層的縱裂和角裂；在塗層表面由於應力集中，塗層表面發生微觀點蝕和深層剝落；沖擊載荷能量的積累，造成塗層試樣硬度變化和塑性變形。

  4. A modified definition of polarization resistance calculated from the equivalent circuit of eis make its value dependent on the grain size. in anodic polarization test ( sweeing and stair - steps ), the maximum ( critical ) current density increases while the passivation potential and breakdown potential lowers with the reduction of the grain size. fegsem images showed the grain growth and pitting corrosion of the nc copper surface, uniform corrosion in the mc copper surface and the broken passivation layer in both surfaces

    在陽極極化實驗（包括掃描法和臺階法）中，致鈍電流雖晶粒尺寸減小而增大，而致鈍電位和擊穿電位都隨著晶粒細化而降低。 fegsem照片發現了納米晶銅的晶粒長大和孔蝕，微米晶銅表面的均勻腐蝕，和兩種銅表面破碎的鈍化膜。
  5. Abstract : in one sintering plant, its no. 1 wagon tipper ' s track sur face occurred corrosive pitting and stacking only after short application, and th is effect the normal production seriously. in order to diagnose the plastic defor mation of the track surface, we made test and fem analysis to it, found the re ason of failure, and put out improving measure

    文摘:某燒結廠1號翻車機在使用較短時間后，導軌表面出現點蝕和堆邊現象，嚴重影響正常生產.針對這一問題，對導軌表面塑性變形進行了實測和有限元分析，從而找出了故障原因並提出了改進措施
  6. Failure : pitting, cratering, or erosion of the surface. obvious and significant deterioration

    失敗：表面出現斑痕、坑凹或侵蝕，明顯且重要的材料毀損。
  7. Cyclic voltammetry indicated that the reaction mechanisms of micro - and nc copper are identical, but the anodic peaks current density of nc copper is much lower than that of mc copper. the potentiometric analysis demonstrated that the pitting corrosion seemed to happen earlier on nc copper surface than on the mc surface. the xrd found cu2o on nc copper surface while no oxide was found on mc copper surface

    陽極極化實驗表明，納米晶銅的致鈍電位、致鈍電流和維鈍電流都比微米晶銅要低。循環伏安法表明兩者的反應機理沒有根本的區別，但對陽極電流峰的電流值來說，微米晶要高於納米晶，陰陽極峰的距離來說，微米晶要近一些。
