为了研究奥氏体不锈钢带在成形过程中的摩擦及变形特性,设计了一种耦合摩擦和变形的试验装置,在试验中分析了耦合变形量和滑动速度对摩擦系数、表层磨损和接触表层马氏体转变的影响。结果表明,在增加耦合变形量与滑动速度的条件下,钢带试样的摩擦系数随试验时间呈现明显的波动下降;对带试样磨损表面的X射线衍射分析表明,较高滑动速度使摩擦表层转变的马氏体组织增多,由于摩擦表层转变的马氏体组织剥离和产生磨粒磨损导致了摩擦系数的上下波动。
In order to study the friction and deformation characteristics of austenitic stainless steel during forming, a test device was designed to couple friction and deformation. The influence of coupling deformation and sliding velocity on the friction coefficient, surface wear and contact surface layer The impact of the transformation of the body. The results show that under the condition of increasing the amount of coupling deformation and sliding velocity, the friction coefficient of the steel strip decreases obviously with the test time. The X-ray diffraction analysis of the worn surface of the strip shows that the higher sliding speed makes the friction The surface of the martensitic transformation of the organization increased, due to the friction surface of the martensitic transformation of the peel and abrasive wear and tear caused by fluctuations in the friction coefficient.
