Anti-corrosion metal powder reinforced concrete and preparation method thereof
The invention discloses anti-corrosion metal powder reinforced concrete and a preparation method thereof, and relates to the technical field of concrete. Nano nickel, nano chromium and nano titanium are embedded in an aluminum matrix through ball milling under the action of a plasma field, mechanical energy generated by ball milling acts on aluminum powder, and electron bombardment is carried out, so that errors in the matrix are proliferated, moved and creeped, a flaky body is formed, a compact oxidation film is more easily generated on the surface, and the anti-corrosion effect is achieved; the nano-nickel, the nano-chromium and the nano-titanium are embedded in the sheet-shaped body under the action of a positive force, so that high-temperature corrosion resistance is realized, then ammonia gas plasma with low discharge intensity is used for generating an electric-thermal coupling effect with aluminum ions, so that aluminum nitride is partially generated as a hard phase in a matrix and cooperates with the nano-nickel to realize relatively strong mechanical properties, and the high-temperature corrosion resistance is realized. And the high-temperature corrosion resistance is further improved.
本发明公开了一种防腐蚀金属粉末增强混凝土及其制备方法，涉及混凝土技术领域。本发明利用纳米镍、纳米铬、纳米钛在等离子体场的作用下，经球磨嵌于铝基体中，因球磨而产生的机械能作用于上铝粉，加上受到电子轰击，使基体内部位错发生增殖、运动和蠕变，形成片状体，更易在表面生成致密氧化膜，实现防腐蚀的效果，而纳米镍、纳米铬、纳米钛在正向力的作用下，镶嵌于片状体中，从而实现耐高温腐蚀性，接着，换成低放电强度的氨气等离子体，与铝离子产生电‑热耦合效应，从而使部分生成氮化铝，为基体中的硬质相，协同纳米镍实现较强的力学性能，并进一步提升耐高温腐蚀性。
