Abstract

本实用新型涉及一种牙轮钻头使用的复合齿。背景技术：牙轮钻头广泛应用于油田、矿山和工程钻探工业，现有的牙轮钻头的切削齿和保径齿是用硬质合金材料制成，在实际应用中，由于硬质合金的硬度不够高，复合齿的使用寿命较短，影响了施工效率。发明内容：本实用新型的目的就是针对现有技术存在的上述技术问题，提供一种硬度更高的牙轮钻头用的复合齿。其技术方案是在现有复合齿的硬质合金齿头外表层沉积一层金刚石涂层。本实用新型的复合齿由于金刚石涂层的极高耐磨性，同时又具有硬质合金的良好性能，其使用寿命大大高于硬质合金复合齿，从而提高了施工效率，节约了施工成本，是现有复合齿的替代产品。

Description

牙轮钻头用复合齿
一、技术领域：本实用新型涉及一种牙轮钻头使用的复合齿。
二、背景技术：牙轮钻头广泛应用于油田、矿山和工程钻探工业，现有的牙轮钻头的切削齿和保径齿是用硬质合金材料制成，在实际应用中，由于硬质合金的硬度不够高，复合齿的使用寿命较短，影响了施工效率。
三、发明内容：本实用新型的目的就是针对现有技术存在的上述技术问题，提供一种硬度更高的牙轮钻头用的复合齿。其技术方案是在现有复合齿的硬质合金齿头外表层沉积一层金刚石涂层。本实用新型的复合齿由于金刚石涂层的极高耐磨性，同时又具有硬质合金的良好性能，其使用寿命大大高于硬质合金复合齿，从而提高了施工效率，节约了施工成本，是现有复合齿的替代产品。
四、附图说明：
图1是本实用新型的一种球形复合齿的结构示意图；
图2是一种圆锥形复合齿的结构示意图。
五、具体实施方式：
参照附图1，在球形复合齿的基体3上部的硬质合金齿头2的外表层，利用气相沉积的方法沉积一层金刚石涂层1。
参照附图2，在圆锥形复合齿的基体3上部的硬质合金齿头2的外表层，利用气相沉积的方法沉积一层金刚石涂层1。
