Padziko roughness

Padziko roughness ndi imodzi mwa muyezo chinsinsi ingatithandize kuzindikira mphamvu mbali. Chiwonongeko anakumana ndi chidutswa mchikakamizo cha katundu variable chifukwa kusonyeza kwambiri za maganizo ndende. Yotsirizira Zikatero, amapezeka pamene pali monyanyira. M'munsi padziko roughness, m'munsi Mwina mapangidwe ming'alu chifukwa kutopa zitsulo. mbali pokonza (liza, kupukuta, akukuta, etc.) kumathandiza kuwonjezeka kwambiri za kutopa mphamvu malire.

M'munsi padziko roughness, ndi bwino anticorrosion katundu katundu. Zimenezi n'zofunika kwambiri pa nthawi imene processing mankhwala si zotheka kugwiritsa ntchito ❖ kuyanika zozitetezera. mwatsatanetsatane, makamaka, akhoza zimachitika zonenepa engine.

Low padziko roughness ndi chofunika kwambiri pairings kuti kukumana zikhalidwe za matenthedwe madutsidwe, zikayamba. Zimenezi angathe kusonyeza atomu, kuwala ndi funde akupanga. Komanso, imfa amakhala ang'onoang'ono kuposa mphamvu mu atomu mu kachitidwe resonating waveguides amakhala capacitance maelekitirodi m'munsi; amachepetsa monga gasi mayamwidwe ndi outgassing mu zipangizo zingalowe ndi ntchito, potero kukonza mbali ya particles adsorbed fumbi, nthunzi, gasi.

Iganizireni akatswiri khalidwe pamwamba taonera mizere lathu anapanga pambuyo Machining kapena mankhwala ena. chigawo ichi ali zimakhudzanso mlingo wa mphamvu wa atolankhani kugwirizana, landings ndithu durability. Mlengi kukamba cholinga zikwapu milandu yovuta. Chotero kungafunikire Mwachitsanzo, okhudza malangizo a gulu la ndege mpweya kapena madzi pa workpiece kapena malangizo a zoyenda wachibale (kutsetsereka) wa conjugates. Yafupika avale kwa osachepera zotheka pamene zofanana malangizo a mbali m'goli ndi malangizo kutsetsereka.

The waviness padziko ndi roughness otsika Tipezeke molondola okwezeka ndi chifukwa osati zinthu opaleshoni ya zinthu conjugate, komanso kufunika zimawayendera odalirika miyezo opangira. workpieces otere ntchito kupanga wokongola maonekedwe kapena kupereka mayiko zinthu zili woyera.

Muyeso wa roughness pamwamba imagwiridwa ngati n'koyenera. Indicators zakonzedwa malinga ndi cholinga zinchito za mankhwala. Ngati amafuna kuti mudziwe anthu amene sanapange, ndiye ulamuliro si anachita pa mlingo wa roughness. Izo ziyenera kuti chonena sumakala ndi ziyenera a zopindika (pamaso pa zipolopolo, mwachitsanzo). Pa nkhani imeneyi, kukhazikitsa ulamuliro wa roughness pamwamba, ulamuliro wa chikoka vuto Kwaletsedwa kwathunthu. Nthawi zina, zofunika angathe mbali payekha chidutswa chimodzi.

roughness kuwunika chitachitidwa pa monyanyira mbiri (amangoona yopingasa). Kuti apange ndege imeneyi yachigawo. Ndi cholinga cha kupatukana monyanyira ena roughness ndi masitepe ndi lalikulu, Kupenda ake imagwiridwa mkati mwa zina, m'dera m'malo zochepa.

Quantification ndi normalization imagwiridwa ndi magawo asanu ndi limodzi. Choncho, kutenga nkhani atatu mkulu-nyamuka chizindikiro ingatithandize kuzindikira padziko roughness (Ra, Rz, Rmax), awiri stepper (S, SM), ndi index, amene amasankha kutalika wachibale wa mbiri thandizo (tp).
