Abstract

Claims (23)

1 . An agricultural metering system, comprising:

a metering system component, comprising:

a meter roller configured to be housed within a meter box and to regulate a flow of particulate material into an air flow, wherein the meter roller comprises:

a substrate formed from a polymeric material; and

a coating disposed on the polymeric material of the substrate, the coating comprising a metallic coating, a ceramic coating, or a combination thereof, wherein the coating is positioned at a surface of the meter roller configured to engage the particulate material.

2 . The agricultural metering system of claim 1 , wherein the metering system component comprises a cartridge configured to be disposed within the meter box, and the cartridge comprises the meter roller.

3 . The agricultural metering system of claim 2 , wherein the cartridge comprises a housing, and the housing comprises:

a substrate formed from a polymeric material; and

a coating disposed on the polymeric material of the substrate of the housing, the coating of the housing comprising a metallic coating, a ceramic coating, or a combination thereof, wherein the coating of the housing is positioned at a surface of the housing configured to engage the particulate material.

4 . The agricultural metering system of claim 2 , wherein the cartridge comprises a housing, and the housing comprises:

a substrate formed from a polymeric material; and

a coating disposed on the polymeric material of the substrate of the housing, the coating of the housing comprising a metallic coating, a ceramic coating, or a combination thereof, wherein the coating of the housing is positioned at a surface of the housing configured to engage the meter roller.

5 . The agricultural metering system of claim 1 , wherein the coating comprises the metallic coating, and the metallic coating comprises nickel, copper, or a combination thereof.

6 . The agricultural metering system of claim 1 , wherein the coating comprises the ceramic coating, and the ceramic coating comprises SiO 2 .

7 . The agricultural metering system of claim 1 , wherein the coating comprises the metallic coating, and the metallic coating comprises a spray coating, an electroplated coating, a vacuum metalizing coating, or a combination thereof.

8 . The agricultural metering system of claim 1 , wherein the coating comprises the ceramic coating, and the ceramic coating comprises a spray coating.

9 . The agricultural metering system of claim 1 , wherein the meter roller is configured to be retrieved from the meter box to facilitate disposition of the coating on the polymeric material of the substrate.

10 . A method of manufacturing a metering system component for an agricultural metering system, comprising:

retrieving a substrate of the metering system component from the agricultural metering system after the substrate is used in operation, and

disposing a coating on the substrate after retrieving the substrate from the agricultural metering system, the coating comprising a metallic coating, a ceramic coating, or a combination thereof, wherein the substrate is formed from a polymeric material, and the coating is disposed on the polymeric material.

11 . The method of claim 10 , comprising pretreating the substrate before disposing the coating on the substrate.

12 . The method of claim 10 , wherein disposing the coating on the substrate comprises disposing the metallic coating on the substrate via a spray, via electroplating, via vacuum metalizing, or via a combination thereof.

13 . The method of claim 10 , wherein disposing the coating on the substrate comprises disposing the ceramic coating on the substrate by spraying a SiO 2 coating on the substrate.
