Description
Technical Field
The invention relates to the field of materials, in particular to a crack stop profile for bonding, fixing and laminating.
Background
Fracture is the primary form of catastrophic failure of a component, the root cause of which is the formation and propagation of cracks from the original defects of the material (profile). The mechanisms of crack initiation and propagation can be largely divided into three categories: crack growth under cyclic loading, crack growth under high temperature creep conditions, and crack growth under stress corrosion. The sudden nature of crack failure makes it a culprit for many major accidents. Thus, a great deal of research is devoted to the prevention and repair of microcracks in components, and the current research is mainly focused on three aspects:
(1) existing crack repair aspects include forming a hard surface alloy layer by mechanical impact, thereby improving the fatigue resistance of the metal surface, as disclosed in patent CN 201610359455.1; the surface microcracks are closed by laser treatment, as disclosed in patent CN 101239432A; the pulse discharge treatment dulls the microcrack tip, reduces stress concentration and prevents crack propagation, as disclosed in patent CN105429203 a; or a composite treatment technique of three techniques, such as patent CN98125434.9, discloses a method for composite treatment of microcracks using mechanical impact and laser impact.
(2) In the aspect of development of the crack-arresting material, microcapsules are arranged in the material, and when cracks propagate to the microcapsules, substances such as repairing agents, curing agents and the like are released, as disclosed in patent CN200710029991.6, so that further propagation of the cracks is prevented; the high-temperature bonding phase is arranged in the material, when the temperature reaches a certain level, the bonding phase melts and fills the microcracks generated, so as to prevent the microcracks from further expansion, as disclosed in patent CN201310526168.1, and the method is more effective in controlling high-temperature creep failure; a crack blocking layer is arranged inside the material to control the expansion of cracks in the material, and the crack blocking layer has a self-repairing function, such as the technology disclosed in patent CN 200980113311.6.
(3) In the aspect of design of the crack-arresting parts, the local reinforcement of stress concentration parts of the components is used for limiting the generation and the expansion of cracks, as disclosed in the patent CN201510981219.9 and the patent CN 201210040846.
The existing crack-stopping materials all need to change the basic structure of the materials greatly, so that the original physical and mechanical properties (such as strength reduction, heat conduction performance reduction and the like) of the materials are affected, and the manufacturing cost of the materials is high.
