For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Figure 1 is a schematic diagram of a structure of a tooling for preparing a thin film pattern on a bearing end surface provided by an embodiment of the present invention, such as Figure 1-2 As shown, the tooling may include an adapter plate 100, a pattern mask plate 300, a pressing plate 400 and fasteners. The adapter plate 100 can be detachably mounted on the thin film processing sample table. An installation space for placing the bearing 200 to be plated is formed between the adapter plate 100 and the pattern mask plate 300. The pressing plate 400 is pressed against the end surface of the pattern mask plate 300 away from the adapter plate 100. The fasteners sequentially penetrate the pressing plate 400, the pattern mask plate 300 and the bearing 200 to be plated and are fastened to the adapter plate 100 as a whole.

[0042] In the above-mentioned embodiment, the adapter plate 100 can be installed on the thin film processing sample stage, and the installation method can be one or a combination of bolt fixing, magnetic attraction, vacuum attraction or bonding.

[0043] The adapter plate 100 can be a single part or a combination of multiple parts, aiming to achieve a reliable connection between the preparation tooling and the sample stage of the coating machine; the pattern mask 300 can be one or multiple to achieve the splicing of different patterns.

[0044] As an alternative implementation, the fastener includes a fastening stud 500 and a fastening nut 600. One end of the fastening stud 500 passes through the pressure plate 400, the pattern mask 300 and the bearing to be plated 200 and is screwed into the threaded hole 102 on the adapter plate 100. The other end of the fastening stud 500 is installed with the fastening nut 600, and the adapter plate 100, the bearing to be plated 200, the pattern mask 300 and the pressure plate 400 are pressed by tightening the fastening nut 600.

[0045] Specifically, as Figure 1-2 shown, the fastening stud 500 and the fastening nut 600 are standard parts determined according to the installation space and quantity, to achieve the pressing action of the adapter plate 100, the bearing to be plated 200, the pattern mask 300 and the pressure plate 400, and the bolt pressing torque is set to 30 N.

[0046] Among them, the quantity of the fastening studs 500 can be one of 1, 3, 5, and can be arranged irregularly or symmetrically.

[0047] As an alternative implementation, the adapter plate 100 has a first bearing positioning structure 101 for positioning the bearing to be plated 200. Among them, as Figure 3 shown, the first bearing positioning structure 101 mainly restricts the radial movement and circumferential rotation of the bearing to be plated 200. The first bearing positioning structure 101 in the figure is not limited to the form shown in the figure, and can be a segmented layout or an installation and mating structure.

[0048] As an alternative implementation, there is at least one threaded hole 102 in the middle part of the adapter plate 100 for cooperating with the fastener. Among them, as Figure 3 shown, the threaded hole 102 can cooperate with the fastening stud 500, and the quantity of the threaded holes 102 can be selected according to the diameter of the bearing to be plated 200. The larger the bearing diameter, the more the quantity of the threaded holes 102 required. The threaded hole 102 in the figure is only a schematic way of connecting the coating sample stage by thread, and in actual situations, other types of connections such as adsorption or bonding can be set according to the installation and positioning method.

[0049] As an alternative implementation, the pattern mask 300 is a ring structure, and is adapted to the end face of the bearing to be plated 200 and is provided with at least one pattern to be processed 301 along its circumference, and each pattern to be processed 301 is at least one; the pattern mask 300 is provided with a positioning hole 302 for cooperating with the pressure plate 400 for positioning.

[0050] Specifically, as Figure 4 shown, the pattern to be processed 301 and the positioning holes 302 on the pattern mask 300 are processed to form a hollow structure by one of the methods of laser processing, etching processing or microfabrication. The pattern to be processed 301 is the required pattern for design, and the positioning holes 302 are used to determine the relative position of the pattern mask 300 when it is attached to the bearing to be plated 200. The actual form and layout of the pattern to be processed 301 include but are not limited to this, and are flexibly set according to specific situations. The number and shape of the shown positioning holes 302 are not specifically limited either.

[0051] As an alternative embodiment, the pressing plate 400 has a second bearing positioning structure 401 for positioning the bearing to be plated 200, and a mask positioning structure 402 for positioning the pattern mask 300.

[0052] Specifically, as Figure 5 shown, the second bearing positioning structure 401 can limit the radial movement and circumferential rotation of the bearing to be plated 200, and the mask positioning structure 402 is used to cooperate with the positioning holes 302 to achieve the positioning of the pattern mask 300. The figure only represents the various components required for the pressing plate 400 to perform its functions, and does not represent the final structure of the pressing plate 400. Multiple structural forms or assemblies can be evolved according to the schematic diagram. The second bearing positioning structure 401 shown in the figure is not limited to the form shown in the figure, and can be a segmented layout or an installation and fitting structure; the mask positioning structure 402 shown in the figure can be designed accordingly according to the positioning holes 302, but to increase flexibility, the number of the mask positioning structures 402 can be not equal to the number of the positioning holes 302.

[0053] Among them, the pressing plate 400 should leave space and not block the pattern to be processed 301 on the pattern mask 300.

[0054] As an alternative embodiment, there is at least one through hole 403 for passing through fasteners in the middle part of the pressing plate 400.

[0058] S300. Deposit a sensitive material on the surface of the bearing to be plated according to the set process parameters;

[0059] S400. After the coating is completed, take out the bearing sample.

[0060] In the above embodiment, the magnetron and ion beam composite sputtering deposition system is of the FJL-560a type, and the process parameters are specifically shown in Table 1 below:

[0061] Parameter Flow rate Air pressure Time Temperature Index 40 sccm 1.2 Pa 10 min 100℃

[0062] Step S400 is specifically to continue installing another pattern mask template in the manner of step S100, complete the preparation of another pattern according to the process parameters similar to step S300, and complete the bearing sample with the pattern.
