Embodiment Construction
[0017] A high-speed laser cladding powder formula suitable for anti-corrosion of jackets in offshore wind power, the alloy powder for high-speed laser cladding is aluminum bronze alloy powder, and the mass percentage composition is as follows: Al: 10%-15%, Ni: 5%-8%, Fe: 4%-7%, Si: 3.2%-3.8%, Mn: 1.3%-2.0%, Zn: 0.1%-0.4%, Cu balance. In this embodiment, the alloy powder for high-speed laser cladding is aluminum bronze alloy powder, and the mass percentage composition is as follows: Al: 13.5%, Ni: 6.5%, Fe: 5.4%, Si: 3.6%, Mn: 1.6%, Zn: 0.3 %, Cu balance.
[0018] The material of the jacket is E36 (alloy structural steel) or D36 (structural steel for hull), and the diameter of the jacket is 1.6m.
[0019] Preferably, the particle size of the aluminum bronze alloy powder is 300-800 mesh, and the bulk density is 4-5g / cm 3 , fluidity0.85.
[0020] A method for anti-corrosion of an offshore wind power jacket, comprising the following steps:
[0021] 1) Put the aluminum bronze a...
