Kwizicelo zamashishini, iipropathi zokukhuhlana kwee-composites zibaluleke kakhulu. Izinto ezichaphazela i-coefficient ye-friction ye-flake graphite composites ikakhulu iquka umxholo kunye nokuhanjiswa kwe-flake graphite, iimeko zokungqubuzana komphezulu, uxinzelelo kunye nobushushu be-friction, njl. imidibaniso:
1. Umxholo kunye nokuhanjiswa kweeflake zegraphite.
I-coefficient ye-friction edibeneyo ixhomekeke kwiqhezu lendawo ye-graphite ye-composite flake. Okukhona umxholo omkhulu we-flake yegraphite kwizinto eziphathekayo, inkulu iqhezu lendawo ye-flake yegraphite kumphezulu wokukhuhlana. Ukongeza, okukhona ukuhanjiswa kwe-flake yegraphite kufana, kokukhona ukugquma kwegraphite kulula ukudibanisa kwiiflakes kumphezulu wokukhuhlana, ngaloo ndlela kuncitshiswe i-friction coefficient ye-composite material.
2. Isimo somphezulu wokukhuhlana.
Imeko yobuso be-friction ibhekiselele kubukhulu kunye nendalo yeprotrusions kwindawo yokukhuhla. Xa iqondo le-cogging lincinci, i-fraction yendawo ye-flake ye-graphite kwi-friction surface ye-composite material iyancitshiswa, ngaloo ndlela ibangele ukwanda kwe-coefficient ye-friction.
3. Uxinzelelo.
Umphezulu wezinto ezidibeneyo zihlala zingalingani. Xa uxinzelelo luncinci, i-junction edibeneyo kumphezulu we-friction yindawo yendawo, ngoko ke i-adhesive igubungele kakhulu, ngoko ke i-coefficient ye-friction inkulu.
4. Ubushushu befriction.
Ubushushu be-friction buchaphazela ngokuthe ngqo i-oxidation kunye nokutshatyalaliswa kwe-graphite lubricating layer kwi-friction surface. Ukuphakama kweqondo lobushushu lokukhuhlana, kokukhona i-oxidation ye-graphite lubricating layer ikhawulezayo. Ke ngoko, okukhona umonakalo omkhulu womaleko wokuthambisa wegraphite, kokukhona uphezulu umlinganiso wokukhuhlana.
