Abstract

The invention discloses a coating material for aircraft titanium alloy fasteners and a preparation method thereof. 5-10 parts of aluminum powder, 3-5 parts of anti-corrosion filler, 1-3 parts of lubricant, 3-6 parts of thixotropic agent, 1-3 parts of plasticizer, 1.5-2.5 parts of dispersant, 2-8 parts of solvent, The invention relates to a coating material for aircraft titanium alloy fasteners. The aircraft titanium alloy fastener coating can have good strength, toughness and lubricating performance, meet the requirements of the fastener use environment, and have good stability.

Description

technical field [0001] The invention relates to a composite material, in particular to an aircraft titanium alloy fastener coating material and a preparation method thereof. Background technique [0002] Titanium alloy fasteners have excellent comprehensive properties such as light weight, high strength, fatigue resistance, and corrosion resistance, and are widely used in various parts of aircraft. However, there is a high potential difference between titanium and aluminum materials. When these parts are in Under the influence of the medium, galvanic corrosion will occur and cause failure. Therefore, protective measures need to be taken to ensure the safety of the aircraft for a long time. The development of modern aircraft parts puts forward higher requirements for the heat resistance, toughness and lubricity of the coating. Requirements, under the action of higher conditions, the original coating will fail. At present, there is no coating material for aircraft titanium all...
