Automotive Coating


The development of powder metallurgy for automotive

With the increasingly stringent regulations on vehicle emissions worldwide, it is necessary to improve fuel efficiency and reduce carbon dioxide emissions. The lightweight automobiles will continue to be a developing trend, using a combination of high-strength alloys, lightweight polymer materials, and powder metallurgy.

The global average of powder metallurgy products per automobile is 9~14kg, while the United States has reached close to  20kg per automobile. Considering the goals to save energy and reduce emissions, industries will use more powder metallurgy processes to produce auto parts in the future. However, the disadvantage of powder metallurgy products is that their strength and wear resistance are not as tough as forgings or castings. Therefore, DAHYOUNG has developed a special coating for powder metallurgy to improve the mechanical properties and optimize hardness, heat resistance, corrosion resistance, and wear resistance, without affecting the products tolerance or accuracy requirements.
