  • Spindle motor component of hard disk driver with composite coating layer and composite coating method thereof
    Patent number: 8106553
    Abstract: A spindle motor component of hard disk with composite coating layer and a composite coating method hereof. The spindle motor component of hard disk includes a motor component base (1) and the composite coating layer which is coated on the base (1). The composite coating layer consists of an electrodepositing coating layer (2) and a spraying coating layer (3). The composite coating method includes a step of coating the electrodepositing coating layer (2) on the surface of the motor component base (1) and coating the spraying coating layer (3) on the electrodepositing coating layer (2), wherein the weight ratio of tin in the electrodepositing coating layer (2) is between 60 ppm to 300 ppm and the weight ratio of tin in the spraying coating layer (3) is no more than 50 ppm.
