Notice
On May 12th a massive fire broke out at Marywilska 44, one of the Warsaw's largest shopping centers. This unexpected incident caused power outages in the surrounding area including the ICM data center where OpenAIRE services run. Efforts are underway to restore the power and to get services back online. Some functionalities will not work properly until then.
We apologize for any inconvenience this may have caused.

ALTERNATIF PENGGANTI PASTA ALUMINA SEBAGAI BAHAN POLISHER UNTUK METALOGRAFI

Abstract

Pemolesan memainkan peran penting dalam persiapan pengujian metalografi. Pemolesan yang kurang baik akan menghasilkan permukaan material yang tidak rata dan kasar sehingga menghasilkan gambar metalografi yang tidak jelas dan sulit didentifikasi. Secara umum material yang biasa digunakan untuk pemolesan adalah pasta alumina. Pasta alumina memiliki harga yang mahal dan diperlukan waktu beberapa menit untuk menghasilkan permukaan yang rata dan halus. Dalam penelitian ini, pemolesan dilakukan dengan menggunakan beberapa bahan selain pasta alumina yaitu magic***, auto***, bras**, ki*, menze*** dan pri** yang dijual dengan harga murah di toko swalayan atau toko online. Analisis dilakukan pada permukaan hasil pemolesan dengan bahan-bahan tersebut dan permukaan hasil etching. Hasil pengujian menunjukkan bahwa material yang dipoles dengan magic*** memiliki permukaan paling halus atau memiliki sisa goresan paling sedikit dibanding dengan bahan-bahan lain bahkan dibanding dengan pasta alumina, namun memiliki kelemahan berupa terbentuknya korosi pada beberapa bagian permukaan. Lama pemolesan terbaik didapatkan pada pemolesan selama 3 menit
