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.

On May 10, 2013, the Ministry of Industry and Information Technology released the “Entry Requirements for the Foundry Industry†to guide the optimization and upgrading of the industrial structure of the foundry industry, curb low-level duplication of construction and blind expansion of production capacity, protect the ecological environment, promote energy-saving and emission reduction, and increase resource and energy utilization levels. Enhance the overall strength of China's equipment manufacturing industry and promote China's transformation from a world-casting country to a founding powerhouse.
On September 9, 2014, the draft revised draft of the “Law of the People’s Republic of China on Prevention and Control of Atmospheric Pollution†began to solicit opinions. This is also the most stringent air pollution prevention and control law in our country. For example, in the draft for exposure, China will establish heavy pollution. The weather monitoring and early warning system shall promptly issue early warning when heavy smog and other heavy pollution weather are likely to occur. The local government will take measures to order the relevant enterprises to suspend production and limit production and initiate emergency response. From this we can see that whether it is to meet the requirements of national laws, regulations and industrial policies, or to meet the needs of the development of the foundry industry, the Chinese foundry industry must take a sustainable road to green casting.
Although China's economic development speed is shifting, it is still in the mid-to-high speed development period. With the recovery of the world economy, China's economy has been transformed from "investment-led" to "innovative-driven", and the national energy-saving emission reduction and recycling economy policies have been gradually implemented. The reform of mixed ownership of state-owned enterprises will inevitably bring new development opportunities to the Chinese foundry industry. Green casting will certainly bring new development springs to the Chinese foundry industry.
Domestic equipment manufacturing green casting welcomes development
After the rapid development of domestic equipment manufacturing industry in recent years, China's foundry industry ranks first in the world in the number of enterprises, castings output, etc., accounting for 40% of the world's total casting production, and the core gap between the "big but not strong" developed casting countries. Emphasis is placed on the gap between product quality levels and development methods. The gap in the development approach is mainly reflected in the fact that our country's foundry industry is still in an extensive development mode. The casting production has high material consumption and energy consumption. It has high waste generation and pollutant discharge, and its comprehensive utilization of resources is low. Poor working conditions, labor protection and safe production protection measures are not in place. This development model does not meet the requirements of the country in building a resource-conserving and environment-friendly society. It is an unsustainable development model.
