The cylinder block is the main body of the engine. It connects the cylinders and the crankcase together. It is the support frame for the installation of pistons, crankshafts, and other parts and accessories. The quality of the cylinder block determines the size and structural characteristics of the engine. It also affects the rigidity and strength of the engine block and relates to the overall layout of the car.
With the requirements of the Chinese government for the construction of a low-carbon economy, the construction of a new engine mass production system is gradually on the agenda. It is reported that by 2020, China's proposed level of emission per unit of GDP will be reduced by 40% to 45% on the basis of 2005. This poses great challenges for the development of automobiles and their key components. As one of the engine's main components, the cylinder block must face the task of introducing modern production management systems and environmental protection technologies such as light weight and electronic control in order to obtain new orders.
In order to achieve the lightweight of the cylinder block, the cast iron, the main production raw material, will be gradually replaced by aluminum. In addition, in order to ensure stability, the ability to effectively control the hardness and wear resistance of materials has also become widespread. The representative of these is a ceramic cylinder block. The ceramic composite cylinder block plating technology is widely used in foreign countries. It uses positively or negatively charged ceramic powder to cause adsorption on the surface of the plated body, and then the metal atoms are in the process of electroplating. The precipitation of the cathode buries the powder therein to form a composite plating layer; since this technology utilizes the dispersion effect of the ceramic powder in the metal plating layer to enhance the entire structure, the hardness, wear resistance, and mechanical properties of the plating layer are improved.
