PCD (polycrystalline daemane)

Polycrystalline cubic boron nitride - Senyesemane khutsufatso PCBN (cubic boron nitride) Lisebelisoa tsa CBN ka kakaretso li sebetsana le likarolo tsa Cast Iron le tšepe !!! Mashome a robong a metso e robong lekholong.

Litšobotsi tsa ts'ebetso ea sesebelisoa sa PCBN:

1: High thatafala le apara ho hanyetsa;

2: Phahameng mogote botsitso le phahameng mocheso thatafala;

3: Ho ba le botsitso bo phahameng ba lik'hemik'hale;

4: E na le mocheso o motle oa mocheso

5: Coefficient e tlaase ea likhohlano;

sebaka sa kopo

Sesebelisoa sa PCBN se loketse theknoloji e phahameng ea lebelo le mahlaseli a holimo

Sesebelisoa sa PCBN se loketse haholo ho itšeha ka lebelo le phahameng la tšepe, tšepe e thata le lisebelisoa tse ling.

Qetella ho qhibiliha ha thepa e koetsoeng (thatafala kaholimo ho HRC55); Ha ho khothaletsoe ho sebetsana le tšepe ea nodular !!!

1: PCD grade 010 e tla khethoa bakeng sa silicon alloy alloy (likahare tsa silicon tse ka tlase ho 11%)

2: PCD sehlopheng sa 025 se khethiloe bakeng sa alloy e phahameng ea silicon aluminium (likahare tsa silicon tse phahameng ho feta 12%)

3: Aluminium e hloekileng (likarolo: e bonolo, haholo-holo ho khomarela, haholo-holo litlhoko tse phahameng tsa lisebelisoa tsa lisebelisoa le tlhahiso)

motsoako oa aluminium

Aluminium silicon alloy ke motsoako oa ho betla le oa ho betla o entsoeng ka aluminium le silicon, ka kakaretso ea silicon ea 11% .AI Si alloy e sebelisoa haholo ho etsa likarolo tse ling tlasa maemo a ho kheloha indastering ea likoloi le indastering ea mochini ka lebaka la khanya boima ba 'mele, mocheso o motle oa mocheso, matla a itseng, boima le ts'enyeho ea ts'enyeho. joalo ka 7%), thepa ea ho tlatsa aluminium silicon alloy e qhibilihisoa e lokile, e atisang ho sebelisoa e le alloy alloy. Ka Al Si alloy e nang le likateng tsa silicon tse fetang ntlha ea Al Si eutectic (likahare tsa silicon ke 12.6%), ha likarolo tsa silicon li le holimo ho 14.5% ~ 25%, ho eketsa palo e itseng ea Ni, Cu, Mg le likarolo tse ling li ka khona ntlafatsa thepa ea eona e phethahetseng ea mochini. Li ka sebelisoa lienjiniking tsa likoloi ho fapana le li-cylinders tsa tšepe ho theola boima ba 'mele haholo.

Mathata a ho sebetsana le motsoako oa aluminium

1. Khetsi e khomarelang ea thipa - ntlha e tlase ea ho qhibiliha, ho chesa mocheso ho bonolo ho baka ho qhibiliha ha lintho le thipa, ho theha leqhubu la pokello ea chip;

2. Ho itšeha deformation - aluminium alloy e na le thatafalo e nyane, polasetiki e phahameng le sebopeho se seholo sa tšebetso nakong ea ho itšeha;

3. Ho khaola ho thothomela - aluminium alloy e na le modulus e nyane ea elastic mme ho bonolo ho hlahisa elasticity nakong ea ho itšeha.

Lisebelisoa tsa aluminium tsa aluminium alloy castings die li arotsoe haholoholo ka:

Aluminium silicon alloy, aluminium silicon alloy alloy le aluminium magnesium alloy:

Aluminium silicon alloy: haholoholo ho kenyelletsa yl102 (ADC1, a413.0, jj.), Yl104 (adc3, a360);

Aluminium silicon alloy koporo: haholo-holo ho kenyelletsa YL112 (A380, adc10, jj), yl113 (3830), yl117 (B390, adc14), ADC12, jj.

Aluminium magnesium alloy: haholo-holo e kenyelletsa 302 (5180, adc5, adc6, jj.).

ADC12 le adc6 ke lisebelisoa tse sebelisoang haholo China. Phapang e kholo lipakeng tsa lisebelisoa tse peli ke hore litaba tsa Si, Fe, Cu, Zn, Ni le Sn tsa ADC12 li phahame ho feta tsa adc6, ha litaba tsa Mg li le tlase ho feta tsa adc6. ADC12 e na le litšobotsi tse betliloeng tsa ho shoa ha mochini o betere, 'me ts'ireletso ea ts'enyeho e tlase ho ea adc6.
