“…The test consists of deformation by a punch with a hemispherical head up of a sample until it breaks in order to determine the maximum of the depth of the indentation left by the penetrator. The penetration depth in millimeters is the Erichsen Index (IE), the most widely used index for assessing the capacity of steel strips deformation [13,14].…”

Within the present work deformability of Ni-P coatings was analyzed on thin strips of low carbon steel, coated with Ni-P layers in correlation with their structure and chemical composition. Thin layers of 2-7 µm were made at immersion times of 5, 10 and 15 minutes and a variable pH of between 4 and 6, at a temperature of 80-85 °C. The deformability was analyzed by applying the Erichsen Test, which measures the deep deformation capacity of the metallic materials. Following the analysis was established the Erichsen Index (IE) the most used index for assessing the deformation capacity of the sheets.The microscopic analysis, performed on the surface of maximum deformation, shows a cracking of the layers with a different aspect depending on pH, the duration of deposition and the initial structure of the layer. The results of the Errichsen test show a good behavior at plastic deformation of the strips covered with thin Ni-P layers.

Bu çalışmada; endüstriyel sektörde tercih edilmesi yaygın olan AL1050 (%99,53 ticari saflıkta) malzemenin, çekme hızı (zımba hızı), numune eni ve zımba çapı değişiminin Erichsen Sabitine olan etkileri deneysel olarak incelenmiştir. Deneysel çalışmalarda tasarımı, imalatı ve kalibrasyonu yapılan tam otomasyonlu Erichsen şişirme donanımından faydalanılmıştır. Deneyler 5 mm/dakika, 6,25 mm/dakika ve 8 mm/dakika zımba hızlarında, TS EN ISO 20482 standardına uygun olarak 8 mm, 15 mm ve 20 mm küresel uçlu zımbalar ile yapılmıştır. Elde edilen Erichsen şişirme deneyi sonuçlarından; zımba çapının 1,5 katı değerine ulaştığı noktadan itibaren numune genişliğinin artmasıyla ve Erichsen Sabiti’nin düzenli artmaya başladığı, numune genişliği zımba çapına eşit olduğunda ise zımba yükünün ve Erichsen Sabiti değerinin düştüğü tespit edilmiştir. Ayrıca, zımba çapının artmasıyla Erichsen Sabitinin arttığı tespit edilmiştir. Tasarımı, analizi ve imalatı yapılan test cihazından elde edilen deneysel bulgular; 0,01 mm hassasiyette ve güvenilir Erichsen Sabiti değerlerini tespit edecek nitelikte bir donanım olduğunu göstermiştir.
