一种陶瓷增强铁基耐磨复合涂层的堆焊方法
摘要：
一种陶瓷增强铁基耐磨复合涂层的堆焊方法，它涉及一种堆焊方法。本发明的目的要解决现有堆焊技术由于受耐磨焊条和耐磨焊丝种类的限制缺少灵活性的问题。方法：首先采用CO2气体保护焊焊接方法，利用注入式堆焊喷头制备陶瓷增强铁基耐磨复合涂层。优点：一、焊层硬度达到HRC40～65;二、不受堆焊材料种类少的限制。三、避免合金元素与陶瓷相的过渡烧损、沉底或上浮、裂纹等问题。本发明主要用于利用注入式堆焊喷头制备陶瓷增强铁基耐磨复合涂层。
摘要（英）：

The invention relates to a build-up welding method, in particular to a build-up welding method for ceramic-reinforced iron-based wear-resistant composite coatings, and aims to solve the problem that an existing build-up welding technology lacks flexibility caused by limitation of types of wear-resistant welding rods and wear-resistant welding wires. The method includes adopting a CO2 gas shielded welding method, and then utilizing an injection-type build-up welding nozzle for preparing the ceramic-reinforced iron-based wear-resistant composite coatings. The method has the advantages that rigidity of weld layers reaches HRC40-65; limitation of few types of build-up welding materials is avoided; transition burning loss, sinking or floating, cracks and the like of alloying elements and ceramic phases are avoided. The method is mainly used for preparing the ceramic-reinforced iron-based wear-resistant composite coatings by the aid of the injection-type build-up welding nozzle.
