Iron-based laser cladding powders are used in the laser cladding process, which is a technique used to apply a protective coating or build up a desired shape on a metal surface. These powders consist of iron as the main component, along with other alloying elements to enhance specific properties.

Iron-based laser cladding powders typically have a controlled particle size distribution and composition to ensure optimal performance during the laser cladding process. They are designed to have good flowability and excellent metallurgical bonding with the substrate material.
The laser cladding process involves melting the iron-based powder using a high-energy laser beam, which is directed onto the metal surface. The molten powder then solidifies and forms a metallurgically bonded layer with the substrate. This layer can provide improved wear resistance, corrosion resistance, or other desired properties to the metal surface.
Iron-based laser cladding powders are commonly used in industries such as aerospace, automotive, oil and gas, and manufacturing, where there is a need for high-performance coatings or repair of damaged components. They offer advantages such as precise control over the coating thickness, minimal heat input, and reduced dilution with the substrate material.
Overall, iron-based laser cladding powders play a crucial role in the laser cladding process, enabling the creation of high-quality coatings and repair of metal components with improved performance and longevity.
Shanghai Industrial and Commercial Bureau sampling quality results of LED lamps released: unqualified rate of 26.1%
According to the news released by the official website of the Shanghai Administration for Industry and Commerce on July 8, the bureau recently concentrated on organizing 23 sales of 5 shopping malls, 7 professional markets and 11 supermarkets in 4 districts of Xuhui, Putuo, Hongkou and Minhang. Lots of removable, fixed, and embedded LED luminaires were tested for quality and quality. After testing, there were 6 batches that were unqualified, and the unqualified detection rate was 26.1%. Among them, 13 batches of portable LED lamps were sampled, 4 batches were unqualified, the unqualified detection rate was 30.8%; 9 batches of fixed-type LED lamps were sampled, 2 batches were unqualified, and failed. The detection rate was 22.2%; one batch of embedded LED lamps was sampled and no unqualified was detected. The sampling inspection found that the detection rate of unqualified in Minhang District and Putuo District was higher, 50% and 40% respectively. The unqualified items of LED lamps are mainly limit, external wiring and internal wiring, structure, heat resistance, fire resistance and tracking resistance, marking and the like. According to the results of the sampling inspection, the industry and commerce department has ordered the relevant operators to immediately stop selling unqualified commodities, comprehensively clean up the inventories and products for sale, implement rectification measures within a time limit, and urge the unqualified commodity operators to publicize in accordance with the requirements of relevant laws and regulations. Measures to protect the legitimate rights and interests of consumers, and legally investigate the operators who sell unqualified products. At the same time, the industry and commerce department reminds consumers to pay attention to the following points when purchasing, using and maintaining LED lamps: 1. When purchasing LED lamps, you should look at them three times. If the product identification is complete, the manufacturer's name, address, trademark, model specification, rated voltage, rated frequency, rated power, etc. should be checked. Check whether the product model matches the model specification of the inspection report and safety certification certificate. The identification is correct; secondly, whether the power cord of the lamp has the CCC safety certification mark, the cross-sectional area of ​​the external wire should be not less than 0.75mm2; the third is to see if the charged body of the lamp is exposed. After the light source is installed in the lamp holder, the finger should not touch the charged metal lamp cap. 2. When purchasing LED desk lamps for children, avoid buying metal casing lamps with high heat source, such as incandescent lamps, tungsten metal lamps, and metal casing lamps; at the same time, pay attention to whether the lamps are stable enough, and tilt the lamps around 6 to see them. Whether it is overturned; choose a table lamp with a higher category of protection against electric shock, such as a Class II luminaire marked with a phrasing number. Third, after buying the lamps, you should carefully check the markings of the lamps and read the instructions for use, and then install and use them; when using LED lamps, if you find that the fluorescent tubes are red at both ends and the lamps are not lit, you should follow the signs of the light source. Replace the aging lamp in time; when cleaning and maintaining the LED lamp, pay attention to the instruction manual. In addition to removing the lamp cover cleaning lamp cavity or replacing the lamp tube, do not easily disassemble the other parts of the lamp, and at the end of cleaning and maintenance, install the lamp as it is.
