Constant amplitude fatigue tests have been carried out on welded steel joints in air and in sea water.The seawater corrosion fatigue tests have been conducted at loading frequency of 0.2 Hz,stress ratio of -1,seawa- ter temperature of about 20℃ and cathodic protection with the potential about-850 mV,SCE.The preliminary results obtained show that the fatigue life of welded steel joints in sea water appeared to be a factor of 2-3 times shorter than in air.The seawater corrosion fatigue tests have also been conducted...

Constant amplitude fatigue tests have been carried out on welded steel joints in air and in sea water.The seawater corrosion fatigue tests have been conducted at loading frequency of 0.2 Hz,stress ratio of -1,seawa- ter temperature of about 20℃ and cathodic protection with the potential about-850 mV,SCE.The preliminary results obtained show that the fatigue life of welded steel joints in sea water appeared to be a factor of 2-3 times shorter than in air.The seawater corrosion fatigue tests have also been conducted to assess the improvement in fatigue strength after TIG dressing of welded steel joints.The preliminary results obtained indi- care that the seawater corrosion fatigue life under cathodic protection appeared to be significantly increased after the welded steel joints were subjected to TIG dressing.

本工作进行了板状焊接钢接头在空气中的常幅疲劳试验;和在海水中的常幅腐蚀疲劳试验(加载频率为0.2Hz,应力比 R=-1,海水温度~20℃,阴极保护负电位~850mV,SCE)。将两者试验结果比较,初步表明,钢接头海水腐蚀疲劳的平均寿命约为空气中的1/2到1/3。本工作还进行了焊缝经过 TIG 熔修的试件的试验,初步结果表明,TIG 熔修处理明显地增加了焊接接头的海水腐蚀疲劳(有阴极保护)寿命.

Because of the cathodic protection system fixed onboard, offshore rigs and the ballast tanks of the merchant ships have comparatively longer life. The traditional sacrifice anode cathodic protection can no longer meet the demand. The paper refered to the design standard for the cathodic system developed by DNV, studied the concepts of preliminary, mean and later-stage protection current densities, and on that basis presents the specific design method and procedures, which serves a good reference in designing...

Because of the cathodic protection system fixed onboard, offshore rigs and the ballast tanks of the merchant ships have comparatively longer life. The traditional sacrifice anode cathodic protection can no longer meet the demand. The paper refered to the design standard for the cathodic system developed by DNV, studied the concepts of preliminary, mean and later-stage protection current densities, and on that basis presents the specific design method and procedures, which serves a good reference in designing the sacrifice anode cathodic protection for the offshore units and ship's ballast tanks. It can be also refered in designing the ship's cathodic protection systems for other laree and medium size ships.

近海工程及运输船舶的压载水舱由于其阴极保护寿命较长,传统的牺牲阳极阴极保护设计方法已不完全符合实际情况。本文参考挪威船级社的阴极保护设计标准,引用初始、平均和后期保护电流密度等概念,提出了具体的设计方法和步骤供近海工程和压载水舱的牺牲阳极阴极保护设计参考,对其它大、中型船舶的船体阴极保护设计也有参考价值。
