On May 17, the Ministry of Commerce issued a notice to supplement the release of the first batch of rare earth export quota for 2012. Twelve companies such as Baotou Iron and Steel Group and China Aluminum Corporation received a total of 9,490 tons of light rare earth export quotas and 1,190 tons of medium and heavy rare earth export quotas, totaling 10,680 tons. According to the notice of the Ministry of Commerce, the enterprises that issued the quotas this time are those enterprises that have passed the second batch of environmental verifications by the Ministry of Environmental Protection.
In the list of supplementary allowances, Inner Mongolia Baotou Rare Earth (Group) High-tech Co., Ltd., which is the largest rare earth group in the north, is still not on the quota list. According to the notice, for companies that have not yet passed environmental verification, such as those that have passed the environmental protection verification of the Ministry of Environmental Protection before the end of July 2012, the Ministry of Commerce will immediately issue quotas; if it has not passed the environmental protection verification of the Ministry of Environmental Protection before the end of July 2012, The Ministry of Commerce will no longer issue export quotas, and the remaining quotas will be allocated separately. In addition, the amount of quotas issued this time is calculated based on the export performance of related companies from 2009 to 2011. The quantity issued is approximately 80% of the company's full-year quota.
The notice also stated that Jiangsu Zhuoqun Nano Rare Earth Co., Ltd., Suining Rare Earth Industry Co., Ltd., and Changshu Shengchang Rare Earth Technology Co., Ltd. (formerly Changshu Shengchang Rare Earths Smelter) have established a joint venture with the controlling shareholders of China Aluminum Corporation. Aluminum rare earth (Jiangsu) Co., Ltd. At the request of the above-mentioned enterprises, the export quotas of Jiangsu Zhuoqun Nano-Rare Earth Co., Ltd., Suining Rare Earth Industry Co., Ltd., and Changshu Shengchang Rare-earth Science and Technology Co., Ltd. were transferred to China Alcoa Rare Earth (Jiangsu) Co., Ltd., a subsidiary of China Aluminum Corporation.
In December last year, the Ministry of Commerce announced the first batch of rare earth export quotas for 2012, of which 11 companies that passed the environmental protection audit obtained the first batch of export quotas of 10,546 tons in 2012; for the 20 companies that did not pass the environmental protection review, the Ministry of Commerce The first set of allowances reserved was 14,358 tons. According to the list of supplementary export quotas announced by the Ministry of Commerce, the amount of the first batch of allowances reserved by the Ministry of Commerce still has 3,678 tons remaining.
Cobalt-based alloy powders are commonly used in laser cladding processes due to their excellent wear resistance, high temperature strength, and corrosion resistance. These alloys typically contain varying amounts of cobalt, chromium, tungsten, and nickel, among other elements, to achieve specific properties.
The laser cladding process involves melting the cobalt-based alloy powder using a high-energy laser beam and depositing it onto a substrate to form a protective coating. This coating helps to enhance the surface properties of the substrate, such as hardness, wear resistance, and corrosion resistance.
Some common cobalt-based alloy powders used in laser cladding include:
1. Stellite: This is a well-known cobalt-chromium-tungsten alloy that offers excellent wear and corrosion resistance. It is often used in applications where high temperatures and abrasive environments are present, such as in oil and gas drilling tools, valves, and pump components.
2. Tribaloy: Tribaloy alloys are cobalt-based alloys that contain varying amounts of chromium, molybdenum, and silicon. They are known for their exceptional high-temperature strength and resistance to galling, making them suitable for applications in the aerospace, petrochemical, and power generation industries.
3. Haynes alloys: Haynes alloys are nickel-cobalt-chromium-molybdenum alloys that offer excellent high-temperature strength, oxidation resistance, and corrosion resistance. They are commonly used in applications where extreme heat and corrosive environments are present, such as in gas turbines and chemical processing equipment.
These cobalt-based alloy powders are available in various particle sizes and can be tailored to meet specific application requirements. They can be used with different laser cladding techniques, such as powder-fed laser cladding or blown powder laser cladding, depending on the desired coating thickness and properties.
Overall, cobalt-based alloy powders for laser cladding provide enhanced surface properties and improved performa
