Abstract

Lapisan Fe-Si-Al-Mg dengan variasi berat ferrosilicon, Mg dan Al yaitu 50(Fe-Si)-37.5Al-12.5Mg, 50(Fe-Si)-25Al-25Mg, dan  50(Fe-Si)-12.5Al-37.5Mg telah dipreparasi pada substrat baja karbon rendah dengan menggunakan teknik pemaduan mekanik (mechanical alloying). Struktur dari lapisan Fe-Si-Al-Mg dipelajari menggunakan XRD (X-ray Diffraction) untuk mengetahui fasa yang terbentuk dan OM (Optical Microscope) untuk mengetahui ketebalan lapisan yang didapatkan. Hasil X-ray Diffraction dan Optical Microscope menunjukkan bahwa lapisan Fe-Si-Al-Mg telah berhasil dideposisikan pada substrat baja karbon rendah. Lapisan Fe-Si-Al-Mg yang terbentuk memiliki fasa intermetalik FeSi2, Mg2Si dan Al0.7Fe3Si0.47. Setiap komposisi menunjukkan ketebalan lapisan yang berbeda. Ketebalan lapisan cenderung menurun dengan meningkatnya konsentrasi magnesium dan berkurangnya konsentrasi aluminium.Kata Kunci: lapisan, Fe-Si-Al-Mg, pemaduan mekanik, fasa, ketebalan.

Abstract

Counterfeiting is an increasing problem for Intellectual Property Rights (“IPR”) protection throughout the world. Counterfeiting activities are generally related to trademark infringements as the counterfeiters are trying to generate instant benefits from the established trademarks around the world by using such marks without consent. Counterfeit products manufactured in People’s Republic of China (“PRC”) might be considered as the greatest evidence of IPR law contravention. The national government has not been successful in decreasing the large number of counterfeiting cases. Therefore, in this article, the counterfeiting in the PRC will be examined initially in order to verify the fundamental concerns and the significantly influential factors in combating counterfeiting. Possible solutions are suggested and considered along with the other issues so that counterfeiting problems may gradually be reduced within the country.
