Abstract

In the manufacturing industry, the importance of joining technologies has been increasing continuously. Joining techniques are widely employed in many fields such as additive manufacturing, bonding semi-products, manufacturing composite and complex structures. Particularly, adhesively bonded joints provide exceptional advantages over conventional joining techniques such as environmental resistance, thermal/electrical resistance, weight-saving and its ability to join dissimilar materials. In the bonding process of high-strength adhesives, surface preparation of adherends play a significant role in the performance of adhesive joints. Although there are many theories on adhesion mechanism, the most accepted and proven theory is ‘mechanical-interlocking’. In the light of mechanical-interlocking theory, desired strength of adhesive joints can be achieved by keeping the roughness of bonding surfaces optimum. Overall, appropriate surface morphology and other procedures increasing the surface energy should be taken into account for surface preparation step of adhesive joint manufacturing.

Özet

İmalat sektöründe birleştirme teknolojilerinin önemi artarak devam etmektedir. Birleştirme teknolojileri yarı mamül ürün birleştirmelerinden kompleks yapılar ve kompozit malzeme üretimleri, eklemeli imalat teknolojilerine kadar her alanda kullanılmaktadır. Bu kapsamda, yapıştırıcılar vasıtasıyla yapılan birleştirme teknolojileri farklı cins malzemelerin birleştirmelerine olanak sağladığı gibi, birleştirilecek malzemelerde deformasyona sebep olmadığından büyük avantajlar sağlamaktadır. Yüksek mukavemekli yapıştırıcı uygulamalarında en önemli işlem yüzey hazırlama süreçleridir. Yapışma mekanizmalarında da en yaygın kabul gören ve ispatlanmış teori mekanik kilitlenmedir. Yüzey hazırlama süreçlerinde, malzemelerin optimum yüzey pürüzlülüğüne sahip olmaları durumunda, bağlantılardan istenen mukavemet değerleri elde edilebilir. Yapıştırıcı bağlantılarda birleştirilecek malzemelerin yüzey enerjisi, hem yapıştırıcı reçineyi absorbe etme, hem de yapıştırıcıyla bağ oluşturma bakımından büyük önem taşır. Yüzey hazırlamada uygun yüzey morflojisi ile birlikte yüzey enerjisini arttırıcı işlemler göz gönünde bulundurulmalı ve uygulanmalıdır.Anahtar kelimeler: Yapıştırıcı birleştirmeler 1, Yapışma mekanizması 2, Yüzey hazırlama 3, Yüzey morfolojisi 4, Katıların yüzey enerjisi 5
