一、关于金刚石钻头的磨损机理金刚石钻头在钻进过程中要发生磨损，关于它的磨损机理研究不够。磨损一般应理解为工作过程中零件或工具的形状和尺寸的逐渐变化。苏联В．Д．库兹涅佐夫对磨损作了如下定义：磨损就是当能量消耗等于摩擦力所作的功时，微粒从固体表面分离，从而使固体质量减少的一种现象。因此就不能把磨损同破损和破坏混淆起来，破损和破坏是在短时间内发生的。磨损是个复杂现象，往往是几种过程的综合。摩擦过程中的磨损分为附着磨损、研磨磨损、扩散磨损、疲劳磨损、冲蚀磨损、热磨损、脆性碎裂等。一般认 First, on the diamond drill wear mechanism Diamond drill bit in the drilling process to wear, wear on its mechanism is not enough. Wear should generally be understood as a gradual change in shape and size of parts or tools during work. Soviet Union Д. Kuznetsov made the following definition of wear: Wear is the phenomenon that when the energy consumption is equal to the work done by the frictional force, the particles are separated from the solid surface, so that the mass of the solid is reduced. Therefore, wear can not be confused with damage and destruction, damage and destruction occurred in a short period of time. Wear is a complex phenomenon, often a combination of several processes. Friction in the process of wear and tear are divided into attachment wear, abrasive wear, diffusion wear, fatigue wear, erosion wear, thermal wear, fragile fragmentation. Generally recognized
