Even if the overall market share of self-owned brand products has reached nearly 30% today, we still face the dilemma of the lack of core component technologies. This is the result of pursuing efficiency and market share. It is also an inevitable manifestation of the external procurement and integration of resource production methods. It is hard to imagine that until today, no Chinese auto company has been able to produce large-scale automatic transmissions. Some auto companies have completely abandoned their independent research and development in this area, hoping to achieve a leapfrog development, that is, jump directly to electric cars or new energy vehicles. It can also be found on the purchase of the engine assembly from the most critical component of the car. Although every autonomous car company is now claiming to be developing its own core engine technology. However, the fact is that of the more than 100 national car companies in China, only 7 of them have purchased engine parts from the company or the group like the European and American multinational car companies, and 35 have purchased from both inside and outside the company. 60 companies only purchase from outside the company. Even car companies like Chery and Geely, which already have some economies of scale, are quite dependent on this fast and inexpensive way: Chery’s ACTECO engine is seen as another form of outsourcing, and there is still a distance from real technology control. However, Geely's "reverse development" is considered to be another R & D investment method. Only pursuing a one-sided scale effect, there is no patience and perseverance to focus on nurturing core technological capabilities, and eventually leading to the gradual loss of market share not only in China, but also in other emerging markets, in the Russian market, its domestic production in the first half of 2007 The company’s market share was 25.7%, compared to 41.3% in the same period of last year, accompanied by a 28.7% increase in the overall market. A blow-out auto market similar to China’s in previous years, the share of domestic cars is appearing in the overall market. Large areas of similar growth in large areas of decline, which could not help but let us ponder and vigilance. The mass production of passenger vehicles by Chinese automakers was around 2000, and the reason why they could develop to a position of overwhelming strength in the Chinese market in 5 to 6 years was because they fully utilized the industrial structure that integrated global resources. The "patchwork"-based technique can only be applied to the stage of the company's pursuit of economies of scale in the early stage of development. It is fundamentally a kind of development philosophy that is quick-money and profit-making, and it will bring about "parasitic" thoughts arising from dependence. When the mistake has been committed, it is best to correct it in a timely manner and take a long-term perspective instead of covering up with the mistakes once made. |
Boride-based powders are commonly used in thermal spray applications due to their high hardness, wear resistance, and thermal stability. Some commonly used boride powders for thermal spray include:
1. Boron Carbide (B4C): Boron carbide is one of the hardest materials known, making it ideal for applications requiring high wear resistance. It also has excellent chemical resistance and thermal stability.
2. Titanium Diboride (TiB2): Titanium diboride offers a combination of high hardness, excellent wear resistance, and good thermal conductivity. It is often used in applications where both wear and heat resistance are required.
3. Tungsten Boride (WB): Tungsten boride powders have high hardness, excellent wear resistance, and good thermal stability. They are commonly used in thermal spray applications for their ability to withstand high temperatures and resist wear.
4. Chromium Boride (CrB2): Chromium boride powders offer high hardness, wear resistance, and good thermal stability. They are often used in thermal spray coatings for applications requiring resistance to abrasion and erosion.
These boride-based powders can be used in various thermal spray processes such as plasma spraying, high-velocity oxy-fuel (HVOF) spraying, and detonation gun spraying to provide protective coatings on surfaces that require enhanced wear resistance and thermal protection.
