Abstract

A high-strength iron-based high-chrome ceramic composite coating for a ship side plate comprises, by weight, 1.6-1.8 parts of graphite powder, 25-27 parts of chromium powder, 4.3-4.6 parts of nickel powder, 4.1-4.4 parts of ganister sand, 0.3-0.4 part of boron powder, 40-42 parts of iron powder, 10-12 parts of TiAl powder, 20-21 parts of B4C powder, 1.2-1.5 parts of nano boron fiber, 0.7-0.9 part of magnesium fluoride, 3-4 parts of zircon powder and 0.2-0.3 part of yttrium oxide. According to the metallurgy coating, the iron-based high-chrome material is used, and superior seawater corrosion resisting performance is achieved; by means of the TiAl and the B4C and alloying treatment, ceramic phases and metal phases can be combined tightly, and the association performance with the iron-based material, the seawater corrosion resisting performance, the impact resisting performance and the abrasion resisting performance are improved; and the impact resisting strength and spalling resistance of the coating are good, the number of gaps is reduced, contact between a corrosion medium and a base body of the ship side plate is effectively prevented, and the corrosion speed is reduced.

Description

technical field [0001] The invention relates to the field of metallurgical coatings, in particular to a high-strength iron-based high-chromium ceramic composite coating for ship side plates and a preparation method thereof. Background technique [0002] There are many ways to solve the seawater corrosion resistance of materials, and surface coating protection is a common method. In this field, in addition to the widely used organic coatings, thermal spraying of zinc-aluminum alloys is also a commonly used long-term anti-corrosion method for marine steel structures. However, thermal spraying requires strict surface pretreatment, and its construction in humid marine atmosphere is limited. In addition, organic coatings and thermal sprayed zinc-aluminum alloy anti-corrosion coatings have poor impact and wear resistance. [0003] The plasma beam surface metallurgy technology uses the plasma arc as the heat source and adopts the method of synchronous powder feeding to clad a lay...
