Mapombi emuchina zvishandiso zvakakosha muindasitiri yekugadzira uye anoshandiswa kugadzira tambo dzemukati muzvinhu zvakasiyana-siyana. Mapombi aya anouya mumhando dzakasiyana uye akagadzirirwa kutsungirira kuoma kwemaitiro ekukweva. Chinhu chakakosha chepombi yemuchina ipendi iri pairi, iyo inokanganisa zvakanyanya mashandiro ayo uye hupenyu hwebasa. Muchinyorwa chino tichaongorora kukosha kwependi nhema uye nitriding mumapombi emuchina, tichinyanya kutarisa pamapombi espiral ane nitrided uye zvakanakira zvawo mumashandisirwo emaindasitiri.
Kuvhara nhema, kunozivikanwawo se black oxide coating, inzira yekurapa pamusoro pemvura inoshandiswa pamapombi emuchina kuti ivandudze mashandiro avo uye kugara kwenguva refu. Kuvhara uku kunowanikwa kuburikidza nemakemikari anoita kuti pombi iite jira re black oxide pamusoro pepombi. Kuvhara nhema uku kunoshanda zvakasiyana-siyana, kusanganisira kuvandudza ngura uye kusakara kwepombi, kuderedza kukweshana panguva yekukwesha, uye kupa nzvimbo nhema yakatsetseka inobatsira pakunyorovesa uye kubvisa machipisi.
Kuisa nitriding, kune rumwe rutivi, inzira yekurapa kupisa inosanganisira kupararira kwegesi yenitrogen pamusoro pepombi kuti igadzire layer yakaoma, isingapfeki. Kuisa nitriding kunobatsira zvikuru mukuwedzera kuomarara uye kusimba kwemapombi emuchina, zvichiita kuti akodzere kupinza zvinhu zvakaoma zvakaita sesimbi isingatsvedzeri, titanium nedzimwe alloys dzine simba guru. Kuisa nitriding kunovandudzawo kuramba kwepombi kubva pakunamira uye kukwesha, dambudziko rinowanzoitika kana uchibata zvinhu zvakaoma kushandisa muchina.
Kune ma "spiral taps", mabhenefiti e "nitriding" anonyanya kuoneka. Ma "spiral taps", anozivikanwawo se "fluted taps", ane dhizaini ye "spiral flute" inobvumira kubviswa kwema "chip" zvinobudirira panguva yekudzvanya. Dhizaini iyi inonyanya kubatsira pakubata maburi asina kujeka kana maburi akadzika, sezvo ichibatsira kudzivirira kuungana kwema "chip" uye ichikurudzira kubuda kwema "chip" zvakanaka. Nekushandisa "nitriding spiral taps", vagadziri vanogona kuve nechokwadi chekuti maturusi aya anochengetedza mipendero yakapinza uye geometries ye "groove", zvichivandudza kuyerera kwema "chip" panguva yekushanda kwe "tapping" uye kuderedza kupfeka kwemidziyo.
Kusanganiswa kwemagadzirirwo emapombi ane nitride nespiral tap kunoita kuti mapombi ane nitride ashande zvakanaka mukushandisa michina yakaoma. Mapombi aya anogadzira shinda dzemhando yepamusoro dzine kupenya kwakanaka, kunyangwe muzvinhu zvakaoma uye mumamiriro ekugadzirisa. Pamusoro pezvo, kuramba kupfeka kwakawedzerwa kunopihwa ne nitriding kunowedzera hupenyu hwemapombi ane spiral taps, kunoderedza kuwanda kwekutsiva maturusi, uye kunobatsira kuchengetedza mari yese mukugadzirwa.
Munzvimbo dzemaindasitiri uko kubereka nekushanda zvakanaka kwakakosha, kusarudzwa kwepombi yemuchina kunogona kukanganisa mashandiro ese emuchina. Nekushandisa mapombi ane nitride ane coating nhema, vagadziri vanogona kuwana kushanda kwakanaka uye kuvimbika panguva yekubaya. Coating nhema inopa imwe nhanho yekudzivirira kubva mukuora nekusakara, nepo kurapwa kwe nitride kuchiwedzera kuomarara uye kusimba kwepombi, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvemidziyo nenzvimbo dzemuchina.
Pamusoro pezvo, kushandisa mapombi esimbi ane nitride kunobatsira kuwedzera kushanda zvakanaka kwemuchina uye kuderedza nguva yekusashanda, sezvo zvishandiso izvi zvichiramba zvichigadzira michina kwenguva yakareba. Izvi zvinobatsira zvikuru mumamiriro ekugadzira akawanda, uko kuderedza shanduko dzezvishandiso uye kuwedzera nguva yekusashanda kwemuchina kwakakosha pakuzadzisa zvinangwa zvekugadzira uye kuramba uchishandisa mari shoma.
Mukupedzisa, kushandiswa kwependi nhema uye kuisa nitriding mumapombi emuchina, kunyanya mapombi anotenderera ane nitrided, kune zvakanakira zvikuru maererano nekushanda, kugara kwenguva refu uye kushanduka-shanduka. Kurapa uku kwepamusoro-soro kunoita kuti mapombi emuchina akwanise kumira nematambudziko emaitiro emazuva ano ekugadzira, zvichipa vagadziri maturusi akavimbika uye anoshanda ekugadzira shinda dzemukati mune zvakasiyana-siyana zvezvinhu. Sezvo tekinoroji ichiramba ichifambira mberi, kuvandudzwa kwemapendi matsva uye kurapwa kwemapombi emuchina kuchawedzera kugona kwavo uye kunobatsira mukuvandudza mashandiro ekugadzira mumaindasitiri akasiyana.
