Abstract

Bakır, özellikle elektriksel yüzey temaslarının bulunduğu durumlarda iyi özellikler göstermektedir. Bu çalışmada, bakır ile takviye edilmiş polilaktik asit kompozitleri eriyik yığma modelleme yöntemi ile imal edilmiştir. Üretilen PLA-bakır kompozitlerinin aşınma davranışları kuru sürtünme ve üç farklı sıcaklık durumlarında (20oC, 50oC, 70oC) ile normal kuvvet 5N, kayma hızı ise 104.7 mm/s alınarak incelenmiştir. Aşınma testleri ısı modülü eklenmiş pin-on-disk aşınma test cihazı ile gerçekleştirilmiştir. Aşındıran karşı malzeme olarak 1040 çelik bilya kullanılmıştır. Üretilen polimer kompozitlerin spesifik aşınma oranları ve sürtünme katsayıları belirlenmiştir. Malzemelerin mikroyapısını irdelemek adına EDX analizleri gerçekleştirilmiş ve aşındırılmış yüzeylerin karakterizasyonu için taramalı elektron mikroskobu (SEM) ile görüntüleri alınmıştır.

Wear characteristics of PLA-Cu composites manufactured by fused deposition modelling under different temperature conditions

Abstract

Copper shows promising characteristics for applications in electrical sliding contacts. In this study, copper reinforced polylactic acid (PLA-copper) composites manufactured by fused deposition modeling (FDM). Wear behaviour of PLA-copper composites under dry sliding conditions at three different temperature conditions (20oC, 50oC, 70oC) was evaluated by using pin-on-disc wear test equipment with attached heating module with 5N load applied at a sliding velocity of 104.7 mm/s. Tests have presented for 1040 steel bead interacting with polymer composite. Specific wear rates and coefficient of frictions of PLA-Cu polymer composites were evaluated. EDX analysis were conducted to examine the microstructure and scanning electron microscopy is used for the characterization of the worn surfaces.
