The results show that the stress of the leaning impact is higher than that of the straight impact. The stress of the leaning impact is the main reason of the failure of the valve plate.

结果表明：阀片倾侧碰撞产生的应力大于正碰撞产生的应力；倾侧碰撞产生的冲击应力正是阀片失效的主要原因。

In acid and salt solution,TiN shows an excell ent corrosion resistance after 100 h immersing test.TiN coating acted as a physi cal barrier between the stainless steel and corrosion media.The corrosion proces s initiated from the pinhole and the corrosion process under the coating is very similar to the pit corrosion form.

结果表明：TiN涂层可以提高材料在中性和酸性溶液中的耐蚀性能，TiN涂层的保护机制为物理屏障作用；镀层的微观结构缺陷是涂层失效的主要原因，涂层下金属的腐蚀行为与孔蚀类似。

The results showed that the performance of the drill pipe joints was in line with standard and the main reason was that the making up torque was inadequate.Drill pipe joints in underground unrestrained tightening-up caused the drill pipe joints to bear the excessive load more than their anti-torque yield strength.

结果表明：钻杆接头的各项性能指标均符合标准规定，失效的主要原因是上扣扭矩不足，钻杆接头在井下无节制旋紧，致使钻杆在井下的自上扣扭矩超过了钻杆接头的实际抗扭屈服强度。

With the appearance of a free span pipeline, its loading types and stress state will be changed. Especially when ocean currents pass through it, a periodical vortex shedding is often produced and induces vibration of the free span pipeline. This type of vibration contributes a lot to the fatigue failure of a free span pipeline.

管跨段的出现改变了海底管线所承受的载荷形式和应力状态，尤其是在海流作用下流经管跨时，常伴随着周期性的涡旋发放，引发管跨段的周期性振动，成为管跨段发生疲劳失效的主要因素之一。
