Method of making a composite sintered powdered material article

Claim 1

A METHOD OF MAKING A COMPOSITE SINTERED POWDERED MATERIAL ARTICLE, COMPRISING PRESSING FIRST AND SECOND MASSES OF PARTICLES OF SINTERABLE POWERED MATERIAL INTO FIRST AND SECOND BRIQUETTES HAVING CORRESPONDING FACES AHAPED WITH APPROXIMATELY MATING SURFACES ADAPTED TO APPROXIMATELY FIT ONE ANOTHER, FORMING ON SAID CORRESPONDING FACES MULTIPLE COMPOSITE SERRATIONS OF LARGER SIZES THAN THAN SIZES OF THE ORIGINAL PARTICLES OF POWERED MATERIAL OF WHICH THE BRIQUETTES WERE COMPOSED, SAID SERRATIONS HAVING RECESSES DISPOSED THEREBETWEEN, EACH SERRATION BEING COMPOSED OF A MULTIPLICITY OF SAID ORIGINAL PARTICLES, PLACING SAID FIRST AND SECOND BRIQUETTES AGAINST ONE ANOTHER WITH THEIR CORRESPONDING SERRATED SURFACES DISPOSES IN OPPOSING ABUTTING ENGAGEMENT WITH ONE ANOTHER AND WITH THE OPPOSING RECESSES BETWEEN THE OPPOSING SERRATIONS FORMING INTERVENING OPEN SPACES, PRESSING THE THUS-ABUTTING BRIQUETTES AGAINST ONE ANOTHER WITH A PRESSING FORCE OF SUFFICIENT MAGNITUDE TO BREAK DOWN THE OPPOSING SERRATIONS INTO PARTICLES ENTERING SAID INTERVENING OPEN SPACES AND FORM A COMPOSITE BRIQUETTE WITH AN INTERVENING LAYER OF RALATIVELY LOOSE INTERMINGLING PARTICLES BETWEEN SAID ABUTTING BRIQUETTES, FURTHER PRESSING THE COMPOSITE BRIQUETTE TO THE DENSITY DESIRED THEREFOR, AND SINTERING THE COMPOSITE BRIQUETTE TO FORM A SINTERED COMPOSITE POWDERED MATERIAL ARTICLE.

Claim 2

A METHOD OF MAKING A COMPOSITE SINTERED POWDERED MATERIAL ARTICLE, COMPRISING PRESSING FIRST AND SECOND MASSES OF PARTICLES OF SINTERABLE POWERED MATERIAL INTO FIRST AND SECOND BRIQUETTES HAVING CORRESPONDING FACES AHAPED WITH APPROXIMATELY MATING SURFACES ADAPTED TO APPROXIMATELY FIT ONE ANOTHER, FORMING ON SAID CORRESPONDING FACES MULTIPLE COMPOSITE SERRATIONS OF LARGER SIZES THAN THAN SIZES OF THE ORIGINAL PARTICLES OF POWERED MATERIAL OF WHICH THE BRIQUETTES WERE COMPOSED, SAID SERRATIONS HAVING RECESSES DISPOSED THEREBETWEEN, EACH SERRATION BEING COMPOSED OF A MULTIPLICITY OF SAID ORIGINAL PARTICLES, PLACING SAID FIRST AND SECOND BRIQUETTES AGAINST ONE ANOTHER WITH THEIR CORRESPONDING SERRATED SURFACES DISPOSES IN OPPOSING ABUTTING ENGAGEMENT WITH ONE ANOTHER AND WITH THE OPPOSING RECESSES BETWEEN THE OPPOSING SERRATIONS FORMING INTERVENING OPEN SPACES, PRESSING THE THUS-ABUTTING BRIQUETTES AGAINST ONE ANOTHER WITH A PRESSING FORCE OF SUFFICIENT MAGNITUDE TO BREAK DOWN THE OPPOSING SERRATIONS INTO PARTICLES ENTERING SAID INTERVENING OPEN SPACES AND FORM A COMPOSITE BRIQUETTE WITH AN INTERVENING LAYER OF RALATIVELY LOOSE INTERMINGLING PARTICLES BETWEEN SAID ABUTTING BRIQUETTES, FURTHER PRESSING THE COMPOSITE BRIQUETTE TO THE DENSITY DESIRED THEREFOR, AND SINTERING THE COMPOSITE BRIQUETTE TO FORM A SINTERED COMPOSITE POWDERED MATERIAL ARTICLE.
