Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

The country’s series of policies on the introduction of the automobile market led to the phenomenon of “blowouts†in the first half of the year. Mini-cars are undoubtedly the “beneficiaries†among them. The frequent actions of multiple manufacturers in the mini-car market also indicate that the competition in the mini-vehicle market is gradually escalating.
â– Joint venture brand will counter the mini vehicle market
In the mini-vehicle market, the self-owned brand models include Chery QQ, QQme, BYD F0, Geely Panda, Chery Ruiyi M1, Changan Benben, Shuanghuan Aristocrat, Lubao and other ten models. The joint venture brands are only Beidouxing, Alto and Le Chi. Three models, it is clear that the overall performance of the independent brand micro-car is better than the joint venture brand.
Although the "sportsmen" in the mini-vehicle market are more from their own brands, with the listing of new Alto in the second half of this year, the joint venture brands have switched their "heads" to the mini-vehicle market. Hyundai Motor once said that it will introduce the i-series of all models in the future, so the mini-car i10 may enter the domestic market. At present, this car has already been listed in Taiwan. Recently, there is also news that the Nissan minicar March will also be made in Dongfeng Nissan; the new SPARK will be launched next year; Honda also said that its new mini vehicle TIF will consider releasing in China. In the high-end market, with the entry of SMART, its rival FIAT500 may also enter the Chinese market.
â– The mini car market entered the subdivision era
A Suzuki brand dealer stated: “Although the self-owned brands are lagging slightly behind joint venture brands in many technologies, they have more price advantages; since joint venture brands have no obvious price advantage, the pursuit of quality products will be the future direction.†The demand and direction will also enable the mini-vehicle market to be divided into three sub-markets: practical mini-vehicles, boutique mini-vehicles and personalized mini-vehicles. The self-owned brands will be mainly used for practical mini-vehicles, and joint-venture brands will focus on boutique mini-vehicles.
For consumers, the entry of joint venture brand micro-vehicles is a good thing, which will give consumers more choice. This “bigger†is not only reflected in the addition of several joint venture brand models, but also reflected in the quality, Price and service.
The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
