General Motors announced on November 21, 2012 that the company’s engineers will work with independent researchers in January next year to jointly study how to improve tire technology to further save fuel. GM has now allocated $5 million to the newly established National Tire Research Center in Virginia. The center has a tire performance testing machine that can help car and tire manufacturers to simulate real-world accidents and improve safety. According to general statistics, tire improvements can increase fuel efficiency by 7%. The center invested USD 11.2 million in tire performance testing equipment. Such a device allows the tire to travel 200 miles per hour to provide data on its operation, performance, torque and braking in different road conditions. GM said that it is important to improve the test specifications of the machine. GM and other automotive engineers can use this data to predict vehicle performance and change tire characteristics to improve vehicle performance. Frank DellaPia, General Motors Dynamics Manager and Managing Director of the Tire Research Center, said in a statement, “Our testing equipment can be said to have risen from a normal telescope to the height of the Hubble Telescope. It has opened up a whole new world and is full of infinite possibilities. Possibly, it can test tire performance in any situation. Currently it is unique worldwide. This is a big step in tire technology." 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
