The exhaust valves of diesel engine on ships , airplanes and tanks are mainly made of Nimonic 80A by forging .

船舶、坦克用柴油机的排气阀主要采用Nimonic80A锻制而成。

Accordingly , when laser power varies in the range of 2750W ~ 4000W , the corresponding matched arc current ranges in 80A ~ 160A .

当激光功率在2750W～4000W时，相应匹配的电弧电流在80A～160A之间。

The experimental results showed that the PU elastomer with hardness of 80A had better cushioning performance and longer operating life , and was more suitable for the cushion condition of the impact tapping system .

结果表明：所选硬度为80A的材料具有较好的综合缓冲性能及较长的使用寿命，更加适合冲击攻丝的缓冲工况。

By combining thyristor switch with large power transistor , large current rectangular pulsed laser power supply with stable smooth top is obtained , pulsed current of 80A and top current fluctuation within 2 % are achieved .
