As can be seen from the table, the addition of graphite network framework, greatly improves the impact flexibility of product so that product
Larger impact can be resisted, increasingly complex environment can be tackled.And the alloying of product surface so that product is more severe
In environment, as obtained stronger corrosion resistance in seawater, extend life of product.
It is skilled to this area although having been made a detailed description to the present invention and being cited some specific embodiments
For technical staff, as long as it is obvious that can make various changes or correct without departing from the spirit and scope of the present invention.
