Claims
- 1. A method of preparing a structurally viable matrix to provide a pattern of abrasive elements comprising:
- covering a plurality of magnetizable protrusion means extending from a base means with a release means for releasing said matrix;
- applying magnetizable particles to said release means;
- orienting said magnetizable particles by means for generating a first magnetic flux along a flux path generally transverse to said base means; and
- applying binding means for at least partially encapsulating said magnetizable particles and forming a structural interconnection therebetween.
- 2. The method of claim 1 including the step of selectively orienting said first magnetic flux and aligning said magnetizable particles therewith prior to applying said binding means.
- 3. The method of claim 1 wherein said binding means is a mixture of braze alloy and a binder.
- 4. The method of claim 1 wherein said magnetizable particles are magnetizable abrasive particles.
- 5. The method of claim 1 wherein said magnetizable particles form structures having triangular cross sections at said preselected locations.
- 6. The method of claim 1 wherein said first flux generating means is positioned beneath said release means and said base means.
- 7. The method of claim 6 including the step of orienting said magnetizable particles by means for generating a second magnetic flux along a flux path generally transverse to said base means.
- 8. The method of claim 7 wherein said second flux generating means is positioned above said release means.
- 9. The method of claim 8 wherein said second flux generating means is oppositely poled from said first flux generating means.
- 10. A matrix prepared according to the method of claim 1.
- 11. A method of preparing an article having a high friction surface using the method of claim 1 and the additional steps comprising:
- removing said matrix from said release means;
- affixing said matrix to a base structure; and
- heating said matrix and said base structure to brazing conditions.
- 12. A method of preparing a structurally viable matrix on an apparatus having a release means disposed on a plurality of magnetized members oriented in a preselected pattern comprising the steps of:
- diffusing magnetizable abrasive particles on said release means;
- at lease partially encapsulating said particles in a fixing means to produce a matrix, curing said fixing means; and
- removing said matrix from said apparatus.
- 13. The method of claim 12 including the additional step of selectively orienting said magnetizable particles by means for generating a magnetic flux prior to encapsulating said particles.
- 14. A method of preparing an article having a high friction surface using the method of claim 12 and the additional steps comprising:
- removing said matrix from said release means;
- affixing said matrix to a base structure; and
- heating said matrix and said base structure to brazing conditions.
- 15. An article having a high friction surface produced according to the method of claim 12.
- 16. A method for preparing an article having a high friction surface comprising:
- applying magnetizable particles to a release means disposed on a plurality of magnetized protrusions;
- applying a fixing means capable of maintaining said particles in predetermined locations before brazing, said fixing means being capable of securing said particles to a base structure after brazing;
- releasing a matrix formed of said abrasive particles and said fixing means from said protrusions,
- affixing said matrix to a base structure; and
- heating said matrix and said base structure to brazing conditions.
- 17. An article prepared according to the method of claim 16.
