Problems solved by technology

[0002] The traditional method of obtaining wear-resistant drilling tools can only be carried out by mechanical processing methods such as heat treatment. The improvement and improvement of the wear-resistant performance of drilling tools is very limited, and the manufacturing cost and expense are relatively high. The requirements of grinding performance lead to various drilling (well) accidents, which greatly increase the cost of drilling (well)

Abstract

The invention discloses an abrasion resistant drilling tool plated with a diamond layer and a manufacturing technology thereof, an extremely thin deposit layer containing the diamond is obtained by electroplating on a conductive metal substrate, and the extremely thin deposit layer plated with the diamond is then bonded to a part of the drilling tool where the abrasive resistance needs to be intensified, forming the abrasion resistant drilling tool plated with the diamond layer. The manufacturing technology thereof comprises the steps of: processing the conductive metal substrate prior to the electroplating, plating the thin diamond deposit layer on the substrate by electroplating, peeling off the diamond electroplating deposit layer from the substrate, and bonding the diamond electroplating deposit layer to the surface of the drilling tool with a strong adhesive to form the abrasion resistant drilling tool plated with the diamond layer. The invention provides a method for conveniently and rapidly applying the plating diamond layer to manufacturing a plurality of strong abrasion resistant drilling tool, and the manufacturing technology thereof is quite easy and readily.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to the invention of a drilling tool for a strong abrasive formation, and also relates to a manufacturing process of the wear-resistant drilling tool. Background technique [0002] The traditional method of obtaining wear-resistant drilling tools can only be carried out by mechanical processing methods such as heat treatment. The improvement and improvement of the wear-resistant performance of drilling tools is very limited, and the manufacturing cost and expense are relatively high. The requirements of grinding performance lead to various drilling (well) accidents, which greatly increase the cost of drilling (well). Contents of the invention [0003] The purpose of the present invention is to provide a wear-resistant drill tool coated with a thin diamond layer instead of the traditional heat-treated wear-resistant drill tool. By adopting a new material and manufact...
