摘　　要：齿轮传动以其优良、可靠的传动性能,广泛应用于各工业领域。齿轮在啮合过程中的表面损伤以及由于过载作用而导致的齿轮轮齿折断是齿轮传动过程中的主要失效形式。因此,研究齿轮的齿面强化方法具有极高的社会和经济价值。根据近几年国内外在材料强化方面的研究进展及在齿轮上的应用,总结和讨论了齿轮的齿面强化方法:表面渗氮和渗碳技术、热喷涂技术、激光淬火技术、喷丸强化技术,以及超声挤压加工技术。并详细介绍和探讨了超声挤压加工技术的原理、强化效果和今后的发展。Gear drive with its good reliable transmission performance, widely used in various industrial fields. In the process of gear meshing, gear tooth broken due to surface damage and overload effect, is the main failure forms. Therefore, the study of the tooth flank strengthening methods has a very high social and economic value. The research progresses of material strengthening and the corresponding applications on gears were reviewed, and the methods of gear tooth flank, such as surface nitriding and car- burizing technology, thermal spraying technology, laser quenching technology, shot peening technology, and ultrasonic extrusion process technology, were summarized in details. Eventually, the principle, reinforcement effect and developing trend of ultrasonic extrusion process technology were discussed.
