It is considered that the carbon gradient of carburized layer can be controlled by hot-rolling deformation rate.
分析认为，可以用热轧形变量大小控制渗碳层的碳梯度。
The gradient PPS/FEP composite anti-corrosive coatings were prepared on carbon steel. The bonding strength of all coating systems was determined by the pull-off test.
在碳钢表面制备了具有梯度结构的PPS/FEP复合防腐蚀涂层，采用拉开法测定了各涂层体系的结合强度。
The results show that the carbon content and carbusintering temperature are the main parameters that influence the formation of gradient structure.
结果表明：在本实验条件下，初始碳含量与渗碳温度是影响梯度结构的主要参数；
