本发明涉及金属陶瓷涂层领域,具体为一种冷喷涂制备Y/Y 2O 3金属陶瓷涂层的方法。 The invention relates to the field of cermet coatings, in particular to a method for preparing a Y / Y 2 O 3 cermet coating by cold spraying.
背景技术Background technique
金属陶瓷是由陶瓷和粘接金属组成的非均质复合材料,陶瓷主要是氧化铝、氧化锆等耐高温氧化物或它们的固溶体,粘接金属主要是铬、钼、钨、钛等高熔点金属。将陶瓷和粘接金属研磨混合均匀,成型后在不活泼气氛中烧结,就可制得金属陶瓷。金属陶瓷同时兼有金属和陶瓷的优点,密度小、硬度高、耐磨、导热性好,不会因为骤冷或骤热而脆裂。另外,在金属陶瓷表面再喷涂一层气密性好、熔点高、传热性能较差的陶瓷涂层,也能防止金属或合金在高温下氧化或腐蚀,金属陶瓷广泛地应用于火箭、导弹、超音速飞机的外壳、燃烧室的火焰喷口等处。Cermets are heterogeneous composite materials composed of ceramics and bonded metals. Ceramics are mainly high temperature resistant oxides such as alumina and zirconia or their solid solutions. Bonded metals are mainly high melting points such as chromium, molybdenum, tungsten, and titanium. metal. The ceramic and the bonding metal are ground and mixed uniformly, and sintered in an inactive atmosphere after molding to obtain a cermet. Cermets have the advantages of both metals and ceramics, with small density, high hardness, wear resistance, and good thermal conductivity, and will not be brittle due to sudden cooling or sudden heating. In addition, spraying another layer of ceramic coating with good air tightness, high melting point and poor heat transfer performance on the surface of cermet can also prevent oxidation or corrosion of metal or alloy at high temperature. Cermet is widely used in rockets and missiles , The shell of a supersonic aircraft, the flame nozzle of a combustion chamber, etc.
传统的热喷涂技术可以用来制备金属陶瓷涂层,如:火焰喷涂、电弧喷涂和等离子喷涂等,由于喷涂时温度偏高,粉末颗粒或线材需要被加热到熔化状态,不可避免地使喷涂材料在喷涂的过程中发生相变、化学反应及辐射等现象,极大降低涂层的性能。Traditional thermal spraying techniques can be used to prepare cermet coatings, such as flame spraying, arc spraying, and plasma spraying. Due to the high temperature during spraying, powder particles or wires need to be heated to a molten state, which inevitably makes the sprayed material Phase changes, chemical reactions, and radiation occur during spraying, which greatly reduces the performance of the coating.
冷气动力喷涂的特点是喷涂颗粒速度高和温度低,发生相变的驱动力较小,固体粒子晶粒不易长大,氧化现象很难发生,可以最大限度的将喷涂粉末的性质保留在涂层中。因此,在制备金属陶瓷涂层时,可以充分避免金属的氧化,将金属的塑性和陶瓷的脆性有效结合在一起。The characteristics of cold air power spraying are high spraying particle speed and low temperature, low driving force for phase change, solid particle grains are not easy to grow, and oxidation phenomenon is difficult to occur. The properties of spraying powder can be retained to the maximum extent in the coating in. Therefore, in the preparation of the cermet coating, the oxidation of the metal can be fully avoided, and the plasticity of the metal and the brittleness of the ceramic can be effectively combined together.
Y 2O 3陶瓷涂层是目前IC装备关键零部件上较有应用前景的一种防护涂层,与传统的阳极氧化铝膜和氧化铝涂层相比,具有更好的耐蚀效果,因而被广泛研究。 Y 2 O 3 ceramic coating is a kind of protective coating with promising application on key components of IC equipment. Compared with traditional anodized aluminum film and alumina coating, it has better corrosion resistance, so Extensive research.
