Cao Naiyu recalled that during the "Eleventh Five-Year Plan" period, the development of the analytical instrument industry in China considered that the last five years were the fastest five years for the development of the industry. The symbol was fourfold: industry scale, operational quality, technological progress, and Structural Adjustment. She pointed out that the data sources for this conclusion include the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection and the Ministry of Science and Technology.
From the perspective of technological progress, China's online analytical instrument industry has basically completed the transition from analog to digital technology in the past five years, and has made great progress in intelligent and networked technologies. A number of technologies have reached or approached the level of international high-end products and have already achieved industrialization. Domestic control systems have entered large-scale projects, breaking the monopoly of foreign companies and have strategic significance for national economic security.
When it comes to the export situation of China's analytical instrument products in 2010, several groups of figures are worthy of attention: the import of 28.954 billion US dollars, an increase of 38.74%; the export of 14.278 billion US dollars, an increase of 34.01%; including imports of scientific instruments 15.73 billion US dollars, It accounted for 45.6% of the instrumentation industry's imports, an increase of 35.23% year-on-year. Although the import figures are much higher than the export figures, Cao Naiyu said with a smile that one industry figure compared the relevant figures and pointed out that the development of the online analytical instrument industry during the “Eleventh Five-Year†period actually exceeded A booming IT industry.
Nickel Based Laser Cladding Powder
Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.
Cobalt based Laser Cladding Powder
Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.
Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.
Iron based Laser Cladding Powder
The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.
WC blended Laser Cladding Powder
Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
