Best Surface Treatment for Piston Rings: Diamond-Like Carbon (DLC)
2024/7/17
With the gradual formulation of EU environmental regulations, traditional electroplating technology is gradually facing restrictions and challenges. These regulations place stringent requirements on processes containing certain metals and chemicals, prompting many industries to look for more environmentally friendly and sustainable alternatives. In this trend, C.T.I. has emerged rapidly with its innovative black diamond membrane technology, bringing efficient and low-environmental-impact solutions to the piston ring market. Diamond-like carbon (DLC) is an amorphous carbon material close to a diamond structure. It is mainly composed of carbon elements and is formed on the surface of the substrate through physical evaporation, chemical vapor deposition, and other methods. It has many excellent properties, including:
High hardness: C.T.I.'s diamond-like carbon has been tested by the Vickers hardness test, and the hardness reaches (Hv0.05) over 2500, which is significantly higher than general electroplating materials, greatly enhancing the wear resistance.
Low friction coefficient: The friction coefficient of traditional electroplating coatings is usually between 0.3 and 0.4, but the diamond-like carbon technology adopted by C.T.I. reduces the friction coefficient to less than 0.04. This not only significantly improves the performance and durability of mechanical components, especially under high-load and high-speed operating conditions.
Corrosion resistance: Diamond-like carbon has excellent chemical stability and can effectively resist various corrosive media and protect parts from damage.
High wear resistance: C.T.I.'s diamond-like carbon significantly extends the service life of mechanical parts due to its exceptional hardness and wear resistance.
High thermal conductivity: The coating has splendid thermal conductivity and can quickly conduct the high heat generated by the piston to the cylinder wall, effectively improving heat energy utilization.
C.T.I. has a profound research foundation in the field of diamond-like carbon and leads the world with U.S. Patent US 905744B2 and Taiwan Patent M300746. These patented technologies cover the preparation methods of black diamond membranes and film layer performance control, providing C.T.I. with strong support for the development of high-performance, high-reliability diamond-like carbon products and surface treatment services. C.T.I. has not only made great achievements in technological innovation, but also actively assumes environmental responsibility and provides the market with high-quality diamond-like carbon environmental solutions.
