Nickel-based composite anti-slip coating and preparation process thereof

Abstract

The invention relates to a nickel-based composite anti-slip coating and a preparation process thereof, and belongs to the field of surface treatment. The process comprises the follow steps that firstly, the surface of base metal is subjected to cleaning, oil removal and sand blasting so as to be roughened; and secondly, the composite anti-skid coating is prepared on the metal surface through adopting a supersonic twin-wire arc coasting method, wherein a bonding layer is made of a NiAl95 / 05 alloy wire, and the surface layer is made of a NiAl80 / 20 composite wire. According to the nickel-based composite anti-slip coating and the preparation process thereof, the nickel-based composite anti-slip coating is high in bonding strength and friction coefficient, and has good wear resistance, impact resistance, chemical solution resistance and the like; and in addition, requirements of anti-skid functions for occasions such as a large ship aircraft take-off and landing platform, an offshore oil platform, a vehicle ferry deck, a ramp of an underground garage can be met.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular provides a nickel-based composite anti-slip coating and a preparation process thereof. It is suitable for anti-slip function on metal surfaces, especially suitable for large naval aircraft platforms, offshore oil platforms, vehicle ferry decks, ramps in underground garages, etc. Background technique [0002] Arc spraying is a thermal spraying process developed in the late 1980s and early 1990s. The prominent features of arc spraying are the use of clean electric energy, high energy efficiency, no pollution to the environment, high spraying efficiency, high utilization rate of sprayed materials, good process controllability, and simple operation. [0003] As early as the 1960s and 1970s, metal-based anti-skid coatings had been applied to aircraft carrier deflectors. The first to be put into use is the nickel aluminate non-slip coating, which is applied to the deflecto...

AI Technical Summary

Problems solved by technology

However, resin-based anti-slip coatings still have the following major disadvantages compared to metal-based anti-slip coatings: ① easy to age and degrade; After that, it dropped to 0.8, while the friction coefficient of the metal-based anti-slip coating has been stable above 0.9 for a long time; ③The wear resistance is insufficient, and the wear resistance of the metal-based anti-slip coating is equivalent to that of cast iron, which is more than 5 times higher than that of the resin-based anti-slip coating; ④Construction And high temperature will volatilize toxic gas, but the metal-based anti-slip coating will not volatilize toxic gas; ⑤The bonding force with the primer is poor, up to 8MPa, while the metal-based anti-slip coating and the substrate can reach more than 15MPa; ⑥ The corrosion resistance life is short, and the corrosion resistance life of the metal-based anti-skid coating can reach more than 15 years
