中国首台4万吨航空模锻液压机在西安热试成功

　　31日，中国首台400MN(4万吨)重型航空模锻液压机在西安阎良国家航空高技术产业基地热试成功，顺利锻造出其首个大型盘类件产品。
　　据了解，400MN重型航空模锻液压机由西安三角航空科技有限责任公司承制，清华大学设计，中国二十二冶制造，是世界上最大的单缸模锻液压机。该项目以生产大型精密航空模锻件为主要目标，投产后将提高航空模锻件的研制和生产水平，促进飞机和航空发动机研制技术，对推动中国航空工业快速发展具有重大意义。
　　该液压机采用了目前国际一流设计和控制系统，是中国大飞机项目的重要基础装备。该液压机本体结构拥有完全自主知识产权，由清华大学以其在钢丝预应力缠绕领域数十年的技术积累为基础，应用最先进的预应力钢丝缠绕剖分-坎合技术、机器人智能缠绕技术等设计而成，解决了压机承载机架、400MN主工作缸、动梁等关键部件的设计和制造问题。制造过程中采用机器人原位缠绕施工技术及重型结构的整体平移、吊装等安装技术，设备总体性能达到了世界先进水平。
　　该项目的建成和投产，可提升中国航空航天装备制造业的设计和制造能力，解决大型钛合金整体框、梁和大型涡轮盘等难变形精密模锻件的设计和制造问题，保障大飞机项目的研制。同时，该设备可广泛服务于航天、船舶、石化、电力、兵器、核电等领域。
　　据悉，目前该项目已获得国内外多家知名航空企业的意向订单，同时受到波音公司、空客公司、普惠、利勃海尔、古德里奇、GE、罗-罗等国际著名航空制造企业的高度关注。

Tungsten Carbide Powder

Tungsten carbide thermal spray powder is a type of powder material that is used in thermal spray processes. It is composed of tungsten carbide particles, which are combined with a binder material to form a powder.

Thermal spraying is a coating process that involves heating the powder material to a molten or semi-molten state and then spraying it onto a surface to create a protective or functional coating. Tungsten carbide thermal spray powder is known for its hardness, wear resistance, and high melting point, making it suitable for applications where extreme wear or high temperatures are present.

The tungsten carbide particles in the powder provide the coating with excellent wear resistance, while the binder material helps to bind the particles together and adhere them to the surface. The powder can be sprayed using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel spraying.

Tungsten carbide thermal spray coatings are commonly used in industries such as aerospace, automotive, oil and gas, and mining, where components are exposed to harsh environments or abrasive conditions. These coatings can provide protection against wear, erosion, corrosion, and high temperatures, extending the lifespan of the coated components.
