The chemical tempering method is a versatile process applicable to glass of various sizes, complex shapes, and thin structures (up to 0.5 mm). In this study, the effects of mechanical washing resistance and weather conditions on both untempered and chemically tempered glass were experimentally explored. Tempered samples exhibit an average Compressive Stress (CS) of 413 MPa (±8 MPa), a Layer Depth (DOL) averaging 20 µm (±2 µm), and Central Stress (CT) averaging 9 MPa (±0.6 MPa). Despite this SEM images show no visible impact on surface morphology post-tempering. However, EDS spectra indicate an increased potassium ratio, confirming successful chemical tempering. The hardness of chemically tempered glass is 6.16 GPa (±0.18), significantly higher than untempered glass at 5.53 GPa (±0.12). In the Free Fall Test, untempered glass drops an average of 16 cm, while tempered glass surpasses 28 cm with no breakage. During the Bending Test, untempered glass bends 6 degrees on average, whereas tempered glass exceeds 13 degrees without breaking. Chemically tempered glass displays enhanced resistance to hydrolysis, with no significant difference noted in dishwasher resistance. Overall, tempered glass demonstrates superior breakage resistance under specified test conditions.

Mekanik Bulaşik Yikama Direncinin Ve Hava Şartlarının Kimyasal Olarak Güçlendirilmiş Kristal Camlar Üzerindeki Etkisinin İncelenmesi

Öz

Kimyasal temperleme yöntemi, çeşitli boyutlarda, karmaşık şekillerde ve ince yapılardaki (0,5 mm'ye kadar) camlara uygulanabilen çok yönlü bir işlemdir. Bu çalışmada mekanik yıkama direncinin ve hava koşullarının hem temperlenmemiş hem de kimyasal olarak temperlenmiş camlara etkisi deneysel olarak araştırılmıştır. Temperlenmiş numuneler ortalama 413 MPa (±8 MPa) Basınç Gerilimi (CS), ortalama 20 µm (±2 µm) Katman Derinliği (DOL) ve ortalama 9 MPa (±0,6 MPa) Merkezi Gerilim (CT) sergiler. Buna rağmen SEM görüntüleri yüzey morfolojisi sonradan temperleme üzerinde gözle görülür bir etki göstermemektedir. Bununla birlikte, EDS spektrumları, başarılı kimyasal tavlamayı doğrulayan artan bir potasyum oranına işaret etmektedir. Kimyasal olarak temperlenmiş camın sertliği 6,16 GPa (±0,18) olup, 5,53 GPa (±0,12) ile temperlenmemiş camdan önemli ölçüde daha yüksektir. Serbest Düşme Testinde temperlenmemiş cam ortalama 16 cm düşerken, temperli cam 28 cm'yi kırılmadan aşar. Eğilme Testi sırasında tempersiz cam ortalama 6 derece bükülürken, temperli cam kırılmadan 13 dereceyi aşar. Kimyasal olarak temperlenmiş cam, hidrolize karşı daha fazla direnç gösterirken, bulaşık makinesi direncinde önemli bir fark görülmedi. Genel olarak temperli cam, belirtilen test koşulları altında üstün kırılma direnci gösterir.
