Description

Ceramic coatings memiliki sifat kekerasan yang tinggi, tetapi di sisi lain ketahanan terhadap beban impak sangat lemah. Hal ini menyebabkan keterbatasan penggunaan ceramic coating pada aplikasi yang memiliki beban impak. Penelitian ini bertujuan mendapatkan suatu metallic composite yang dapat meningkatkan sifat mekanik ketahanan impak dari ceramic coating. Sifat mekanik yang meningkat ini didapat dengan cara merekayasa serbuk (powder) paduan ceramic-metal sehingga diperoleh paduan metal dalam suatu matriks ceramic atau ceramic matrix composite (CMC). Serbuk CMC kemudian dideposisikan menggunakan High Velocity Oxygen Fuel (HVOF) thermal spray coating. Deposisi dan karakterisasi CMC coating berbasis tungsten carbide (WC) dan Alumina (Al2O3) pada specimen mild telah dilakukan pada tahun 2009. Pengujian impak menunjukkan bahwa ukuran reinforced partikel fasa metal pada matriks keramik berpengaruh terhadap ketahanan repeated impact. Kemampuan keramik (yang memiliki sifat dasar brittle) untuk menyerap energi impak meningkat sebesar 5 sampai dengan 30 kali bila dibandingkan dengan WC12Co original dan hardchrome plating. Pada tahun 2010 dilakukan deposisi CMC berbasis Cr3C2 untuk aplikasi tahan panas sampai dengan 870°C beserta karakterisasinya dan aplikasi (uji coba) pada komponen roll steel mill (pinion shaft wire rod mill). Hasil pengujian repeated impact menunjukkan CMC berbasis Cr3Cr2 memiliki ketahanan impak sampai dengan 200 kali pada stainless steel (SUS304) substrat. Adapun ketahanan terhadap korosi temperatur tinggi menunjukkan jumlah siklus pemanasan 870°C dan pendingin (di dalam air) sampai dengan 31 siklus. Siklus pemanasan dan pendinginan di udara sampai dengan 100 siklus tidak menunjukkan retakan (crack) pada coating. Pada tahun 2011 dilakukan optimasi parameter spraying untuk meningkatkan deposition efficiency untuk CMC dengan reinforced partikel 10-30 u-m, pengujian stress corrosion cracking dan uji coba pada aplikasi komponen dengan ketahanan aus dan impak pada temperatur tinggi. Hasil penelitian diharapkan memiliki prospek yang sangat baik dengan terbukanya penggunaan coating jenis ini untuk aplikasi di bidang energi, transportasi, hankam, dan pertambangan. (2011)
