Abstract
An abrasive material is fabricated. The material is made of bamboo charcoal. The charcoal has vascular bundles and abrasive particles are uniformly distributed and fixed on inner surfaces of the vascular bundles. Thus, the abrasive material can be used with self-sharpening for grinding, polishing, lubricating, etc.
Claims9
A bamboo charcoal composite abrasive material, comprising
- a bamboo charcoal carrier, said carrier having a plurality of vascular bundles as pores;
- a coating layer, comprising a metal coating on an inner surface of said vascular bundles in said bamboo charcoal carrier;
- and
- a plurality of abrasive particles, said abrasive particles being uniformly distributed in said metal coating.

A method of forming a bamboo charcoal composite abravise material, comprising steps of:
- (a) providing a bamboo charcoal carrier having a plurality of vascular bundles as pores;
- (b) processing said carrier into a certain length and grinding a sectional end surface of said carrier to obtain a flow entry plane;
- (c) sinking said carrier into a solution and releasing air in said vascular bundles of said carrier through ultrasonic vibration;
- (d) providing a tank, said tank containing a solution of a coating material with abrasive particles uniformly distributed;
- (e) transferring said abrasive particles into said vascular bundles of said carrier by fluid pressure;
- and
- (f) forming a coating layer on an inner surface of each of said vascular bundles of said carrier to fix said abrasive particles on said vascular bundles.
