The noise reduction effect of ceramic coating on the chassis is mainly reflected in the following aspects:
Reduce frictional vibration noise
In terms of friction between components: Among the numerous components of the chassis, such as the piston rod and oil seal of the shock absorber, and the spring and mounting seat, friction is generated due to relative motion during vehicle operation. Ceramic coatings have the characteristic of low friction coefficient. When applied to these areas, it can make the friction between components smoother, reduce the vibration caused by friction, and thus reduce the "squeaking" sound or other abnormal friction noise caused by it, making the vehicle quieter when driving.
Transmission component situation: For the transmission components of the chassis, such as half shafts, friction may also occur during operation due to coordination with other components. Ceramic coating can reduce this friction, suppress vibration and noise transmission caused by friction, and control the noise generated by the chassis during power transmission to a certain extent.
Suppress impact noise
Dealing with road impact: When a car is driving on bumpy roads, the impact of the road will be transmitted to various components of the chassis through the tires, such as the suspension system's springs, shock absorbers, etc., which will continuously expand and contract to cushion these impacts, easily generating impact noise. Ceramic coatings, with their good matching of elastic modulus and hardness, can help these components better absorb and disperse impact energy, reduce the instantaneous high-energy vibration and accompanying impact sounds caused by impact, and improve the noise performance of the chassis when dealing with complex road conditions.
Improving structural stability: Ceramic coatings are applied to parts such as frames and chassis connectors to enhance their wear and corrosion resistance, maintaining the integrity and stability of the chassis structure. A stable structure is less likely to loosen or deform when subjected to impact, which reduces the additional noise caused by structural changes, such as avoiding "clicking" sounds caused by loose chassis connectors.
Isolate external noise transmission
Forming a protective barrier: The ceramic coating itself covers the surface of the chassis and can serve as a barrier layer to some extent, isolating some noise generated by external road surfaces, airflow, etc. from entering the vehicle. Although it does not have the same strong sound insulation effect as specialized sound insulation materials, it can also play a certain auxiliary role in reducing the transmission of external noise through the chassis structure to the interior of the car. Combined with other sound insulation measures inside the car, it helps to create a quieter driving environment.
However, it should be noted that the main function of ceramic coatings is not dedicated to noise reduction, and their effect on chassis noise reduction is limited. They mainly improve chassis performance, reduce wear, and enhance protection, while also playing a positive role in reducing noise. To achieve better chassis noise reduction, it is usually necessary to combine various methods such as professional sound insulation, sound-absorbing materials, and optimizing the chassis structure.
