Abstract
The invention discloses a hot dip coating Zn-Al-Ni alloy, a preparation technology and a hot dip coating method. The hot dip coating Zn-Al-Ni alloy comprises, by weight, 99.88% to 99.92% of Zn, 0.04% to 0.06% of Al and 0.04% to 0.06% of Ni. During the preparation, Zn is melted and heated to a temperature in a range of 550 DEG C to 600 DEG C, Al foil is added and stirred with ceramic rods, so that the Al foil is dissolved completely, Ni foil is added and stirred, and heat is preserved for two hours after the Ni foil is dissolved completely to enable the Ni foil to be spread evenly. According to the hot dip coating Zn-Al-Ni alloy, the preparation technology and the hot dip coating method, defects in the prior art are overcome, large improvements are provided for coating surface conditions by adding Al and Ni elements simultaneously instead of adding Al and Ni elements independently. Zinc slag can be reduced, the coating surface smoothness can be improved apparently, the coating super-thick phenomenon can be inhibited, the abrasion resistance is enhanced, the abrasion coefficient is small, and the coating corrosion resistance is improved, so that advantages of adding Al and Ni elements independently are reflected comprehensively.
