“…Their nature and shape differ depending on the goals. The reinforcement of the second phase can be hard oxides (Al 2 O 3 and TiO 2 ) [4] or carbide particles (SiC [3], WC [5], B 4 C [6], diamond [7] and nitride [8]). Solid lubricants (PE [9], PTFE [10], graphite [11] and MoS 2 [12]) can reduce the friction coefficient.…”

“…Although Ni-Fe and Ni-Co alloys have good hardness at room temperature, their softening phenomenon are evident when the temperature is rising, the hardness of Ni-P alloy, however, can be enhanced by precipitate strengthened effect which is a result of heat treatment and it promotes the hardness significantly [7]. Among these, Ni-P alloy possesses high hardness, high strength and other superior mechanical properties; so that, electroless Ni-P alloy or composites have been approved that they are suitable used in automobiles, aviation, food, printing, chemical, and other instruments [8][9][10][11][12]. Unfortunately, the operating conditions of electroless technique are difficult to alter and are unsuitable for thick film coating deposition.…”

“…Beberapa faktor yang mempengaruhi penggabungan patikel keras/halus ke dalam matriks electroless Ni-P yaitu bentuk dan ukuran partikel, densitas relatif partikel, muatan partikel, ketidakreaktifan partikel, konsentrasi partikel dalam bath, metode dan derajat agitasi, kesesuaian partikel dengan matriks dan orientasi bagian yang dilapis [6]. Reddy et al [7] merekomendasikan bahwa untuk mencapai integritas yang lebih baik antara partikel dan matriks electroless Ni-P, ukuran partikel harus menjadi kecil sehingga dapat diikat oleh matriks.…”

ABSTRAK STUDIPENGARUH VARIASISUHUPERLAKUANPANASTERHADAPSTRUKTURMIKRO DAN KOROSIFITAS PADA PELAPISAN SS 410 MENGGUNAKAN KOMPOSIT Ni-P-NANO PARTIKEL Al 2 O 3 .Pelapisan material Stainless Steel 410 dengan komposit Ni-P-nano powder Al 2 O 3 menggunakan metode electroless kodeposisi sangat tergantung pada tingkat penggabungan lapisan komposit tersebut antara matriks Ni-P dan penguat nano partikel Al 2 O 3 Hal ini berpengaruh pada keunggulan sifat lapisan komposit seperti ketahanan korosi yang baik, laju deposisi yang cepat, keseragaman deposit yang dihasilkan dan ketahanan kimia yang baik. Pada penelitian ini, parameter yang divariasi adalah suhu perlakuan panas setelah proses electroless kodeposisi. Penelitian ini bertujuan untuk mengetahui fenomena strukturmikro, fasa dan kristalinitas, komposisi kimia dan distribusi unsur di permukaan coating, dan ketahanan korosi komposit coating Ni-P-nano partikel powder Al 2 O 3 . Substrat yang digunakan yaitu Stainless Steel 410 di-pretreatment untuk mengaktivasi permukaan, kemudian direndam dalam larutan yang terdiri dari nikel sulfat, natrium hypophosphite, ammonium sulfat, sodium asetat, lead asetat dan serbuk nano alumina. Substrat direndam selama 60 menit, dalam suhu proses 90±2 o C dengan kecepatan putaran 150 rpm. Karakterisasi sampel dilakukan menggunakan alat SEM-EDS, XRD, dan CMS. Dari hasil percobaan menunjukkan terdapat perbedaan visual permukaan substrat antara logam dasar, setelah proses electroless coating dan setelah perlakuan panas. Berdasarkan variabel percobaan, untuk suhu perlakuan panas yang optimum adalah 400 o C, dimana terbentuk strukturmikro dari nodular menjadi butiran yang lebih teratur dan merata serta memiliki ketahanan korosi yang paling baik. ABSTRACT THE STUDY OF INFLUENCE HEAT TREATMENT TEMPERATURE ON THE MICROSTRUCTURE AND CORROSIVITY OF COATING SS 410 USING COMPOSITENi-P-PARTICLE NANO Al 2 O 3 . The Ni-P-particle nano powder Al 2 O 3 composite coating have been prepared by electroless codeposition method. It has advantage that the process does not require an electrode, fast deposition rate, good corrosion and wear resistance. In this study, the variable parameters is the heat treatment temperatures after electroless codeposition process. The aim of this research is to determine microstructure phenomenon, phase and crystalinity, chemical composition and distribution on coating surface, and corrosivity Ni-P-nano powder Al 2 O 3 composite coating. The substrate is used stainless steel 410. Substrates have been pre treated in order to activate the surface. Then, substrate immersed in solution that consisting of nickel sulfate, sodium hypophosphite, ammonium sulfate, sodium acetate, lead acetate dan nano alumina powder. The substrate
