A sakamakon rashin ma'ana stacking na fasteners, lye saura a kan surface, forming surface tsatsa da alkali kuna, ko rashin dace selection na quenching man sa fastener surface tsatsa.
1. Gurbacewar da ake samu yayin kurkura
Bayan quenching, an tsaftace kayan haɗin tare da siliki mai tsaftacewa sannan kuma a wanke. M abu ya bayyana a saman. An bincika kayan ta hanyar infrared spectrometer kuma an tabbatar da cewa silicate ne na inorganic da baƙin ƙarfe oxide. Wannan ya faru ne saboda ragowar silicate akan farfajiyar fastener bayan kurkura bai cika ba.
2. A stacking na fasteners ba m
Bayan tempering fasteners nuna alamun discoloration, jiƙa tare da ether, bari ether volatilize kuma sami sauran m sauran, irin abubuwa ne babban abun ciki na lipids. Yana nuni da cewa abubuwan da ake tsaftacewa suna gurɓatar da kayan ɗamara ta hanyar tsaftacewa da kuma kashe mai a lokacin kurkura, wanda ke narkewa a yanayin zafin zafin jiki kuma yana barin tabo mai ƙonewa na sinadarai. Irin waɗannan abubuwa suna tabbatar da cewa farfajiyar mai ɗaure ba ta da tsabta. An yi nazari tare da infrared spectrometer, cakuda man tushe ne da ether a cikin man fetur. Ether na iya fitowa daga ƙari na man fetur. Sakamakon bincike na quenching man a cikin raga bel tanderun tabbatar da cewa fasteners da kadan hadawan abu da iskar shaka a cikin quenching man saboda rashin ma'ana stacking lokacin dumama, amma shi ne kusan sakaci. Wannan al'amari yana da alaƙa da tsarin tsaftacewa, maimakon matsalar kashe mai.
3. Ragowar saman
An yi nazarin ragowar farin da ke kan babban ƙarfin dunƙule ta infrared spectrometer kuma an tabbatar da cewa phosphide ne. Ba a yi amfani da ma'aunin tsabtace acid don tsaftace tankin kurkura ba, kuma binciken tankin kurkura ya gano cewa tankin yana da ƙarancin ƙarancin carbon. Ya kamata a zubar da tanki akai-akai, kuma a duba matakin maida hankali a cikin tankin kurkura akai-akai.
4. Alkaki kuna
High ƙarfi dunƙule quenching zafi saura blackening yana da uniform, santsi mai baƙar fata surface. Amma a cikin zobe na waje akwai wurin bayyane orange. Bugu da ƙari, akwai wuraren da haske blue ko haske ja.
An gano cewa jajayen wurin da ke kan dunƙule yana faruwa ne sakamakon ƙonewar alkali. Wakilin tsabtace alkaline mai ɗauke da chlorides da mahadi na calcium zai ƙone na'urorin ƙarfe a lokacin maganin zafi, yana barin tabo a saman na'urar.
A surface alkalinity na karfe fasteners ba za a iya cire a cikin quenching man fetur, sabõda haka, da surface konewa a high zafin jiki austenite da aggravates rauni a mataki na gaba na tempering. Ana ba da shawarar a wanke da kuma wanke kayan ɗamara sosai kafin magani mai zafi don cire ragowar alkaline gaba ɗaya wanda ke haifar da ƙonewa ga masu ɗaure.
5. Kurkure mara kyau
Don manyan masu ɗaure girman, ana amfani da quenching maganin ruwa na polymer sau da yawa. Kafin quenching, ana amfani da wakili mai tsaftacewa na alkaline don tsaftacewa da kurkar da kayan haɗi. Bayan quenching, fasteners sun yi tsatsa a ciki. Bincike tare da na'urorin infrared spectrometers ya tabbatar da cewa ban da baƙin ƙarfe oxide, akwai sodium, potassium da sulfur, wanda ke nuna cewa fastener yana makale a cikin ciki na alkaline tsaftacewa, mai yiwuwa potassium hydroxide, sodium carbonate ko makamancin haka, yana inganta tsatsa. Ana duba kurkurewar abin da ya wuce kima kuma ana ba da shawarar maye gurbin ruwan kurkure akai-akai. Bugu da ƙari, ƙara mai hana tsatsa a cikin ruwa kuma hanya ce mai kyau.
