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.

China's mining machinery industry currently has two problems: First, the overall strength of the mining machinery industry enterprises is not strong, most companies in the scientific research, new product development, technological transformation and corporate management and other aspects of energy and capital investment are in a standstill. The types of domestic mining machinery products, especially key equipment that are urgently needed for national construction, cannot meet the requirements, and there are problems such as low product technology content, low product added value, unstable product quality, and low labor productivity of all employees, resulting in the production of mining machinery manufacturing enterprises in China. The growth rate of output value is not commensurate with the growth rate of profits. Second, there are problems in product variety, technology, quality, and service, resulting in a low actual contribution of the domestic mining machinery industry to mines. Taking metallurgical mines as an example, there are 1,180 kinds of equipment currently in use, and China's self-sufficiency is only about 26%, and most of them are equipment with low technological content and low quality requirements. The remaining 74% still need to be imported. Domestically produced equipment, especially high-tech mobile equipment, such as full-surface boring machines, mining vehicles, excavators, and scrapers, has a large gap compared with imported equipment. To this end, experts propose ways to improve the innovation capabilities of the mining machinery industry: First, the mining machinery manufacturing industry should adopt different forms of joint ventures with foreign companies and domestic professional design institutes, including the formation of a group, consortium, introduction of technology, introduction of talents, etc. At least we must strive to adopt a joint design method for an engineering project. We must first intervene and improve it to achieve a win-win situation. Secondly, it is necessary to establish and improve the application laboratory of advantageous specialties as soon as possible to conduct research on application technologies of products and manufacturing processes. The laboratory should be highly-started and based on practicality, including test theory and methods, test equipment and scale, and control and inspection techniques, and foreign advanced technology should be introduced when necessary. In addition, relevant institutions of higher learning at home and abroad are not only the bases for the training of mining machinery technicians, but also the origins of the basic theories and experimental techniques of mining machinery. They must rely on their strength and adopt different forms of cooperation and cooperation with them.
Point out that improving innovation ability is the key to the development of China's mining machinery industry
Since entering the 21st century, China's mining machinery industry has ushered in new opportunities for development. However, the technology foundation of China's mining machinery industry is relatively weak. Since the reform and opening up, the mining machinery industry has used the market-for-technology as the main method to improve product technology, and at the same time it has to face the grim situation of foreign competitors investing and setting up factories in China. Relevant experts suggest that China's mining machinery industry must seize opportunities and speed up development, first of all to make efforts in scientific research and technological innovation and independent innovation.
