Abstract
The present disclosure relates to disk separator plates that include a coating to increase the water contact angle of the exterior surface of the disk separator plate so as to decrease its wettability. The present disclosure also involves hard disk drives that include such a disk separator plate and related methods of forming such a coating.
Claims20
A coated, disk separator plate comprising:
- a) a disk separator plate;
- b) an outer coating;
- and
- c) a surface underlying the outer coating, wherein the surface has a first water contact angle value, wherein the outer coating has a second water contact angle value, wherein the second water contact angle value is greater than the first water contact angle value, and wherein the coated, disk separator plate is adapted to be mounted inside a hard disk drive in a non-movable manner and adjacent to at least one rotatable, recording disk.
1 more element
A method of making a coated, disk separator plate, the method comprising:
- a) providing a disk separator plate having on outer surface, wherein the outer surface has a first water contact angle value, and wherein the disk separator plate is adapted to be mounted inside a hard disk drive in a non-movable manner and adjacent to at least one rotatable, recording disk;
- and
- b) applying an outer coating over the outer surface, wherein the outer coating has a second water contact angle value that is greater than the first water contact angle value.
