Claim:
A method of forming and assembling at least two parts together, comprising the steps: a. forming at least two separate parts in a manner that leaves a network of interconnecting porosity in each part wherein at least one part is selected from the group consisting of (1) a part made by spraying glue down and sprinkling metal powder into the glue, and (2) a powder metal part made by pressing and at least one part is selected from the group consisting of (1) a part made by spraying glue down and sprinkling metal powder into the glue, (2) a perforated metal part, and (3) a metal foam part; b. sintering each part that is formed from spraying glue down and sprinkling metal powder into the glue and sintering each powder metal part formed from pressing such that each sintered part continues to maintain a network of interconnecting porosity; c. assembling the sintered parts together; d. causing a fill material to be infiltrated into the assembled parts to form an infiltrated assembly; and e. curing the infiltrated assembly.
