Al2O3-CeO2-ZrO2-Ni system milling process of dispersion and phase change


Larger enterprises, mergers are conducive to large-scale automated production. After 1990, Metal Powder Industry Federation, the United States began keeping statistics on corporate mergers in North America, PM data,[link widoczny dla zalogowanych], since 1990, the powder metallurgy industry in North America were 129 mergers took place in 2007, the business community in North America occurred PM 7 times mergers, powder metallurgy in North America since 2008 occurred in 1 business mergers. According to sales statistics, the powder metallurgy industries and enterprises can be divided into four categories: the first annual sales of more than 200 million US dollars for the enterprise, the second annual sales of $ 75,000,000 as a 2 billion US dollars between companies, The third category is the annual sales of US dollars in 2500-7500 between the companies, the fourth annual sales of less than $ 25,000,[link widoczny dla zalogowanych],000 for the enterprise. 2007 North American PM parts market size of about 23 billion US dollars, in terms of sales, the top 20 companies account for about 80 of a total of PM parts market. Macroeconomic situation and the market is facing changes in the powder metallurgy industry in North America continue to invest in the development of new technologies, new metal powder, equipment and process development, and promote high-performance materials and new application areas appear PM. Some North American manufacturer of metal powders are being developed with higher density and better performance of new materials, including a metal powder production companies are developing a single by single pressing the sintered density can be achieved 7.5g/cm. Material. The company has also developed a gear manufacturing projects, through the gear to the surface densification treatment, the surface can make the gears to reach full density, the density of the gear of the core to 7.5g/cm.. Another metal powder manufacturers have developed a powder forged connecting rods can increase the fatigue limit of the new material 3O. A powder metallurgy parts production enterprises will deal with simple parts of the surface shape of the densification of powder metallurgy technology to improve the application to handle complex shapes and sprocket gear. Scientific and technological development in North America are working for a number of soft magnetic composite materials in the field of electronic technology to find in the market. In the traditional powder metallurgy applications, the use of copper has declined,[link widoczny dla zalogowanych], but in the field of thermal management and biological science, certainly the development prospects of the application of copper and copper possess anti-microbial properties, may cause the copper in the field of health care new applications. North American press manufacturers are developing new technologies,[link widoczny dla zalogowanych], it was reported that as many as 11 steps have been trial of powder metallurgy parts products , the new press can be compressed using a more precise near net shape parts, the maximum pressure generated by the new press reached 2700t, press enterprises in North America has developed a hybrid servo system, new heating and powder temperature and pressure transmission system is also being developed. Metal Powder Industry Federation and the US business community to continue through the American Metal Powder Industry Federation Technical Committee and the powder metallurgy technology centers to invest in new technology. Previously mentioned metal powder industry federation of the United States carried out a project for a car powder metallurgy parts catalog, is now nearing completion, the car can be used to determine PM parts catalog automotive PM parts used in total, can also be used guide the development of powder metallurgy technology in vehicle manufacturing new applications. Powder Technology Center since 2006 in a single full-density powder metallurgy materials and pressed to create a new field of powder metallurgy material fatigue data has invested more than 2O million,[link widoczny dla zalogowanych], the new powder metallurgy materials will increase the determination of fatigue data using the powder metallurgy products, design engineers confidence. Investment in new technology is the key to the future development of powder metallurgy industry, the development of powder metallurgy industry in North America has experienced many ups and downs, the North American powder metallurgy industry into the development of every difficult time, always adhere to usher in the next stage of development boom. Powder metallurgy industry still has tremendous potential for development is a relatively young industry, there will be a lot of innovation there, from the 2008 World Conference on Powder Metallurgy Conference and issued a total of tungsten nearly 500 presentations to see this trend, although the North American auto market in an unprecedented change, powder metallurgy industry outlook remains bright.
