发明名称 Hard Surfacing Non-Metallic Slip Components for Downhole Tools
摘要 A slip component for a downhole tool has a bearing surface that is hard surface treated. The slip component, which can be a slip or other component of a slip mechanism used on a packer, bridge plug, or other downhole tool, is composed of a non-metallic base material, such as plastic, composite, or ceramic. To hard surface treat the slip component, at least the bearing surface is positioned relative to an ion sputtering apparatus. An intermediate layer is first bonded onto the bearing surface by ion sputtering an intermediate material onto the non-metallic base material of the slip component. Then, the bearing surface of the slip component is positioned relative to an electrosparking apparatus, which has an electrode composed of a selected external material for depositing on the slip component. Using the electrosparking apparatus, an external layer is bonded at least on the bearing surface.

主权项 1. A method of hard surfacing a slip component for a downhole tool, the slip component having a bearing surface and being composed of a base material, the base material being non-metallic, the method comprising: positioning at least the bearing surface of the slip component for hard surface treatment; bonding an intermediate layer onto at least the bearing surface by ion sputtering an intermediate material onto the non-metallic base material; and bonding an external layer at least on the intermediate layer by electrospark depositing an external material to at least the intermediate material of the intermediate layer.
