ABSTRACTSpectroscopy technique is used for various applications, for example in archaeology, in order to analyze samples of floors, including material excavation sites. In this work the floor samples that were found in two rooms belonging to a house in a residential Hispanic area, at different stratigraphic levels corresponding to the classical period, as well as samples that were collected in two deposits of lime (El Refugio and El Llano) around the site mentioned were analyzed. The characterization of the samples of the archaeological site Chingú in Tula de Allende in the state of Hidalgo was carried out by using Scanning Electron Microscopy (SEM) to observe the morphology of the samples and Energy Dispersive X-ray Spectroscopy (EDS) to analyze the composition of cementitious material of the floors and natural material of lime deposits. Comparing these samples with other archaeological works of literature, the morphology and composition of manufactured floors will be discussed.

Implantasi ion dapat meningkatkan sifat mekanik seperti kekerasan bahan yang akan digunakan untuk komponen dan peralatan proses manufaktur. Implantasi ion dipengaruhi oleh jenis ion dopan, waktu dan energi yang digunakan. Penelitian ini dilakukan untuk mengetahui pengaruh energi dan waktu implantasi ion titanium nitrida terhadap kekerasan dan struktur mikro pada baja VCL 140. Implantasi dilakukan pada arus berkas tetap 10 yA. Variasi waktu 60, 70, 80, 90, 100, 110, 120 menit, energi 75 keV dan variasi energi 15, 30, 45, 60, 75, 90 dan 100 keV dengan waktu implantasi 100 menit dilakukan untuk mendapatkan kekerasan optimum. Uji Kekerasan menggunakan metode Vickers dengan beban 10 gram dan waktu 10 detik. Topografi dari lapisan TIN diamati menggunakan scanning electron microscopy (SEM) dan komposisi kimia dari lapisan TIN dianalisa menggunakan energy dispersive spectroscopy (EDS).Kata kunci : Implantasi ion, VCL 140, kekerasan
