Lisebelisoa tsa carbon ke tsa lisebelisoa tsa porous. Kakaretso ea porosity ea lihlahisoa tsa carbon ke 16% ~ 25%, 'me ea lihlahisoa tsa graphite ke 25% ~ 32%. Ho ba teng ha palo e kholo ea li-pores ho tla ba le tšusumetso e mpe ho thepa ea 'mele le ea lik'hemik'hale le ts'ebetso ea lisebelisoa tsa carbon. Ka mohlala, ka ho eketseha ha porosity, bongata bo bongata ba lisebelisoa tsa carbon boa fokotseha, ho hanyetsa hoa eketseha, matla a mochine a fokotseha, khanyetso ea lik'hemik'hale le ho bola ea senyeha, 'me ho kenella ha likhase le metsi hoa eketseha. Ka hona, bakeng sa lisebelisoa tse ling tse phahameng tsa ts'ebetso ea khabone le lisebelisoa tsa khabone ea sebopeho, compaction ea impregnation e tlameha ho kengoa ts'ebetsong.
Merero e latelang e ka finyelloa ka ho kenngoa le kalafo ea compaction:
(1) fokotsa haholo porosity ea sehlahisoa;
(2) Eketsa bongata ba lihlahisoa le ho ntlafatsa matla a mochini oa lihlahisoa:
(3) Ntlafatsa tsamaiso ea motlakase le ea mocheso oa lihlahisoa;
(4) Fokotsa ho phunyeletsa ha sehlahisoa;
(5) Ntlafatsa khanyetso ea oxidation le khanyetso ea kutu ea sehlahisoa;
(6) Tšebeliso ea ho kenngoa ha lubricant e ka ntlafatsa ho hanyetsa ha sehlahisoa.
Phello e mpe ea ho inregnation le densification ea lihlahisoa tsa carbon ke hore coefficient ea ho atolosa mocheso o eketseha hanyenyane.
