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

In this work, Si, Ge element composition distribution in Ge /Si1-xGex:C /Si substrate structure has been characterized and modified by planar scanning energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). The Ge /Si1-xGex:C /Si substrate samples are grown by chemical vapor deposition (CVD) method. The accuracy of EDS value can be improved by ~ 32%. And the modified EDS results indicate the Ge distribution in the Ge/Si1-xGex:C/Si sub structure.

A liga Zn-22%Al apresenta uma microestrutura complexa, tanto no estado bruto de fusão, como após envelhecimento, devido à transformação eutetóide (β → α + η). O objetivo desse trabalho é relacionar a morfologia das fases presentes em lingotes brutos de fusão e após envelhecimento com a taxa de solidificação. Amostras dos lingotes da liga Zn-22%Al foram analisadas por microscopia eletrônica de varredura (MEV) e EDS (Energy Dispersive Spectroscopy). A estrutura α + η com morfologia lamelar em amostras brutas de fusão transforma-se em uma textura refinada tendendo a globular-equiaxial após o envelhecimento. Observou-se que a dureza das amostras está fortemente relacionada com a morfologia da estrutura α + η. Por outro lado, a composição e a morfologia das fases são conseqüências da taxa de solidificação e resfriamento.

AbstractSamples of the bodies and elytra of Entomoscelis americana Brown were analyzed separately by X-ray energy-dispersive spectroscopy. Discriminant analysis revealed that the chemoprints of the bodies of newly-emerged beetles (1 wk old) were distinct from those of post-aestivation beetles (9- to 10-wk old). However, the chemoprints of the elytra of newly-emerged and post-aestivation beetles were not as different as those of the bodies as demonstrated by the overlap in the plot of the first two canonical variables. The variances of the mean difference of individual variables between newly-emerged and post-aestivation groups generally were smaller for elytra than for bodies. This suggests that the chemoprints of the elytra of E. americana are more stable than those of the bodies and consequently the elytra should be more suitable than the bodies in insect dispersal studies utilizing the X-ray energy-dispersive spectroscopy technique.
