Problems solved by technology

However, the coating still has the following disadvantages: (1) it is easy to age and degrade, which is unavoidable for all organic materials, and the harsh environmental conditions of the ocean will greatly accelerate this process; (2) due to insufficient wear resistance, the coating The coefficient of friction is unstable. The friction coefficient of the organic anti-skid coating can reach 1.4 at the beginning, and it will drop to 0.8 after 2 years; (3) The thermal shock resistance i

Abstract

The invention discloses an iron-based composite structure high-temperature anti-corrosion and anti-skid coating and a preparation method thereof. The coating comprises a SAM2X5 amorphous alloy anti-corrosion bottom layer (2) and an iron-based amorphous alloy/ceramic anti-skid top layer (1). The iron-based amorphous alloy/ceramic anti-skid top layer (1) is composed of alloy powder and ceramic powder. The alloy powder is prepared from, by mass percent, 31wt% of iron, 28wt% of chromium, 12wt% of boron, 11wt% of cobalt, 10wt% of nickel and 8wt% of silicon. The mass of the ceramic powder is 10%-70%of the total mass of the iron-based amorphous alloy/ceramic anti-skid top layer (1). The coating is high in friction coefficient, coating bonding strength and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a laser cladding iron-based high-temperature resistant anti-slip coating and a preparation method thereof. Background technique [0002] Anti-slip coating is a functional material with anti-slip effect. It can improve the friction of the surface of the object and form a non-slip surface with a high friction coefficient to reduce the sliding of people, vehicles and other objects on the surface of the object. Fall accidents have been widely used on ship decks, offshore oil drilling platforms, and coastal facilities. [0003] As we all know, the marine environment is a very harsh and corrosive environment. In addition to the basic performance of improving friction, the anti-skid coatings applied on ship decks and offshore platforms also need to have good corrosion resistance and anti-ultraviolet aging performance. And marine climate resistance, while the anti-skid c...
