中文摘要:以未经过表面工艺强化的低强度汽车前桥和经过表面工艺强化的高强度汽车变速箱齿轮为对象,对汽车零件经过疲劳极限以下小载荷强化前后,表面硬度的变化规律及其微观原因进行了试验研究和分析。结果表明,小载荷强化后,低强度前桥的表面硬度随着其强度的提高而提高;高强度变速箱齿轮的表面硬度随着其强度的提高而降低;小载荷强化所引起的结构微观组织变化是其表面硬度变化的主要原因;对于汽车零件表面硬度的变化而言,强化和损伤的作用效果相同。

Abstract:

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
