Iyo huru yekucheka michina yelaser yekucheka muchina isimbi isina tsvina, alloy simbi, simbi, aluminium, zingi, magnesium uye zvimwe alloy zvinhu.Zvinhu zvakasiyana-siyana zvine kuoma kwakasiyana uye matambudziko akasiyana ekucheka.Nyanzvi inoteveralaser yekucheka muchina mugadziriVarume-Luck vanotsanangura kuoma kwekucheka kwelaser kune yakajairwa simbi uye yakakwirira-tembiricha alloys.
1. Izvo zvinhu zvine urombo hwekupisa conductivity
Kana iyo laser yekucheka muchina ichicheka alloy, inoburitsa yakawanda yekucheka kupisa, iyo inotakurwa nepombi yekumberi, uye muromo webanga unotakura tembiricha yekucheka laser ye700-9000 °.Pasi pechiito cheiyi tembiricha yakakwira uye simba rekucheka, iyo yekucheka mupendero inoburitsa epurasitiki deformation, bonding uye diffusion kupfeka.
2. Simba guru rekucheka laser
Simba rema superalloys rinodarika 30% rakakwirira kupfuura iro remasimbi alloy anowanzo shandiswa mumhepo turbines.Pane tembiricha yekucheka inopfuura 600 ° C, kusimba kwenickel-based superalloys kuchiri kwakakwira kupfuura kweakajairika alloy simbi.Iyo unit yekucheka simba yeasina kusimbiswa yakakwirira-tembiricha alloy iri pamusoro pe3900N/mm2, nepo iyo yakajairwa alloy simbi inongova 2400N/mm2.
3. Huru hwekuita basa kuomesa
Semuenzaniso, kuoma kweiyo isina kusimbiswa substrate yeGH4169 ndeye HRC37.Mushure mekucheka nesimbi laser yekucheka muchina, iyo yakaomeswa layer inosvika 0.03mm ichaumbwa pamusoro, uye kuomarara kuchawedzera kusvika paHRC47, nekuomarara dhigirii inosvika 27%.Chiitiko chekuomesa basa chine simba guru pahupenyu hwepombi ine oxidized fronts, kazhinji zvichikonzera kupfeka kwakasimba kwemuganho.
Zvichienderana, zvinhu zvakajairika zviri nani kucheka, uye yakakwirira-tembiricha alloy zvinhu zvine hurema hwepamusoro zvakanyanya kuoma kucheka.Mishonga yakasiyana yekucheka inofanira kupiwa kune zvinetso zvakasiyana-siyana zvekucheka.Kuti uwane mamwe mibvunzo nezve laser yekucheka, ndapota bvunza Men-LuckLaser yekucheka michinamugadziri.
