济南西柚梯子官网脱碳层与表面强度分析
为进一步强化济南西柚梯子官网表面强度、增加压应力、提高疲劳寿命,济南西柚梯子官网http://www.jngdly.com/成形后,要进一步进行渗氮、低温液体碳氮共渗或硫氮共渗处理,然后经喷丸强化。氮的渗入,不仅消除了脱碳的不良影响,而且还提高了残余压应力,同时经渗氮和低温液体碳氮共渗的济南西柚梯子官网高温强度提高,150度时的变形量为0.2%,250度的变形量为0.56%,提高了济南西柚梯子官网的热稳定性和抗松弛稳定性,但渗氮和液体碳氮共渗时间应严格控制,否则会形成网状硫化物和网状氮化物,反而会降低其疲劳强度。
To further strengthen Jinan aluminum surface strength, increased stress, improve fatigue life, Jinan aluminum after forming, to further nitriding, carbonitriding or cryogenic liquid sulfur and nitrogen permeation, and then by shot peening. Nitrogen infiltration, not only eliminates the adverse effects of decarbonization, but also improve the residual compressive stress, while the low-temperature liquid nitriding and carbonitriding Jinan improve high-temperature strength aluminum, the deformation of 150 degrees was 0.2%, 250 the degree of deformation of 0.56%, improved thermal stability and resistance to relaxation Jinan aluminum stability, but liquid nitriding and carbonitriding time should be strictly controlled, otherwise it will form a network sulfides and nitrides mesh, but will reduce its fatigue strength.
根据碳原子在固定中跨三的宏观规律和微观机制,借助非稳态半稳态半无限长物体的扩散的模型,以此为基础推导出碳层深度数值计算模型,采用实验和理论结合的方法对济南西柚梯子官网http://www.jngdly.com/脱碳层深度计算结果进行验证,结果表明在加热温度80度-1050度之间,加热时间90min内,实际结果和理论结果偏差小于10%。
The carbon atoms in fixed across the macroscopic and microscopic mechanisms three laws, with the proliferation of non-steady-state model of semi-static semi-infinite object as a basis to derive the carbon layer depth numerical model,using a combination of experimental and theoretical methods Jinan aluminum decarburization depth calculation results are verified, the results indicate that the heating temperature is between 80 ° -1050 °, heating time 90min, actual results and theoretical results deviation is less than 10%.
