According to the US "Automotive News" reported on May 21, the General Motors Corporation announced that it will launch four recalls in the United States, including cars, SUVs and trucks, totaling 2.42 million. Accumulated more than 13.6 million vehicles. GM expects its second-quarter recall to be approximately $400 million, most of which is used to cover the costs of a recent recall, including $500 million in five recalls announced last week. The four recalls announced by GM include: 1.3 million 2009-2014 Buick Encore, Chevrolet Traverse, GMC Acadia and Saturn Outlook for 2009~2010, because the front seat belt of the car is prone to wear and tear, which increases the risk in the car accident. 1.1 million vehicles of the 2004-2008 Chevrolet Mai Rui Bao and the 2005~2008 Pontiac G6 sedan, because the shift cable of the four-speed automatic transmission is easy to wear, so that the shift lever does not match the indicated gear position. The recall is a continuation of the 2007-2008 Saturn Aura sedan recall in late April, which has similar problems with Mai Rui Bao and G6. GM said that the shifting cable of the shifting device may break, causing the driver to fail to shift or turn off the fire. It is reported that the current problems of Mai Rui Bao and G6 models have caused 18 accidents and one person was injured. The Aura model involved 28 accidents and 4 people were injured. The 1402 Cadillac Escalade and the Escalade ESV were sold last month because passenger side airbags may not be fully deployed in a car accident. The 58 models of the 2015 Chevrolet Silverado HD and GMC Sierra HD are at risk of fire. The incident has increased the number of recalls by GM to 29 this year, involving more than 13.6 million vehicles in the United States, some of which may be double-counted due to multiple recalls due to safety issues. According to the report, last week, GM and the National Transportation Safety Administration (NHTSA) reached an agreement to pay a $35 million fine and improve internal security processes. It also said that stricter security measures are being taken to detect problems earlier and to address long-standing issues. Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.

Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
