Waa maxay toogashada toogashada?
Shot peening waa hanaan shaqo qabow oo loo adeegsado abuurista lakab walaaca cadaadiska si loo wanaajiyo sifooyinka farsamada ee birta. Xiijinta Shot waxay u isticmaashaa olol toogasho ah (bir bir wareegsan, dhalooyin ama walxaha dhoobada ah) si ay ugu dhufato dusha birta xoog ku filan soo saarista caagga. Adeegsiga gubashada toogashada ayaa caabiyeyn kartaa dusha birta si ay wax uga badasho astaamaha farsamada ee dusha birta.
Faa'iidada ugu weyn ee toogashada toogashadu waa dib-u-dhigga ama ka hortagga ku-dillaaca qeybaha sare ee walbahaarka walxaha culus.
Waxaan u beddeli karnaa waxsoosaarkaan liita iyo maaraynta walaacyada gantaalaha loo yaqaan 'stresssile'n' oo loo rogo culeysyo harsan oo sii kordhaya nolosha adeegga, lana dheereeyo nolosha qaybaha.
Hawshani waxay soo saartaa walwal culus oo walbahaar ah oo kujira dusha sare ee walxaha. Cadaadiska murugada leh wuxuu caawiyaa ka hortagga gariirka maxaa yeelay dilku kuma fidi karo deegaanka cadaadiska ee lagu abuuro ubax.
Kireynta walxaha gaagaaban ee loo yaqaan 'tensile residual stress' waxaa laga soo saaraa nidaamka daaweynta dusha sare ama habka kuleylka ee daaweynta sida dilitaanka, shiidida, iyo foorarsiga. Burburkan haraadiga ah ee gantaalaha culus wuxuu yareynayaa qaybaha nolosha.
Shot peening waxay u rogi kartaa walax haraaga gantaalka culus culeyska haraaga ah, taas oo si weyn u kordhisa wareegga nolosha iyo awoodda ugu badan ee qaybta.
