Iranian Firm Makes Device for Nano-Polishing of Cylindrical Parts’ Surface
“In this process, using abrasive nanoparticles and special grinding and rotating mechanisms, we have designed a device that polishes and abrades parts and brings the final surface quality to less than 100 nanometers,” said Ali Khoshanjam, the managing director of the technological company.
“The device is used in advanced medical industries, specially in the production of medical prostheses like femoral heads and knee and hip implants, where higher surface quality leads to increased durability and longevity of these parts,” he added.
Noting that in addition to the medical field, this device is also used in the plastic molding industry and micrographic laboratory equipment, Khoshanjam said, “Using nanoparticles, we have produced an abrasive paste that polishes the surface of parts to a quality of less than 100 nanometers, while eliminating the need for expensive traditional tools for polishing parts with specific geometries.”
In a relevant development in 2023, researchers at a knowledge-based company in Iran were able to improve the durability of compressors in oil and gas industry by up to 300 times using ultra-hard coating equipment.
According to a report by the Iran Nanotechnology Initiative Council (INIC), Hassan Jahdi, the managing director of the Iranian technological company said that producing ultra-hard coating equipment using the PVD method is the main field of activity of their company.
He pointed to the importance of using coatings in the industry, saying, "In some parts of compressors, the use of coating can increase the durability of the parts significantly."
“Nanocoating technology has become really popular in industry that it is known as a mother industry. The reason for this is the role that coatings play in an industrial product. In various industries, we are faced with parts that have different mechanical properties, durablity, wear and corrosion resistance, and we can apply special properties to the surface through coatings to increase the lifespan of the parts,” Jahdi said.
“In the oil and gas industry, we use nano-coating to reduce corrosion and bring it under control,” adding, “Oil extraction and exploitation take place in special conditions. This industry has a very corrosive working condition. But if coating is used, it can help reduce rate of corrosion.”
“In gas turbocompressors, coating is applied to control the wear and corrosion. It is considered a high-tech technology in the world. Increasing the efficiency and lifespan of these compressor parts, which are usually very expensive and important parts, is one of the applications of coating,” the engineer explained more.
