Formation of Surface Nanoaustenite and Properties of 3Cr13 Steel Induced by Pulsed Electron Beam Irradiation under Melting Mode

The surface of 3Cr13 martensitic stainless steel was irradiated by high current pulsed electron beam (HCPEB). The microstructures of the irradiation surface were characterized by X-ray diffraction and electron microscopy. After HCPEB irradiation, formation of a melting layer with depth of about 4 μm on the irradiated surface was determined. Further microstructural investigations indicate that the surface melted layer consists of nanoaustenite and ultrafine carbide particles, which primarily appear at grain boundary triple junction. Additionally, the microhardness and corrosion resistance of the irradiated surfaces was improved significantly. The formation of the nanoaustenite layer induced by HCPEB irradiation was believed to be the dominating reasons for the improvement of comprehensive performance of the material surface.

The surface irradiation of 6063 aluminum alloy by high current pulsed electron was conducted with the aim of replacing the complicated pre-treatment in the processes of electroless plating. To explore the microstructure changes, optical metallography, SEM (scanning electron microscope), XRD (X-ray diffraction) analyses were carried out, and the sliding tests were used for the detection of wear resistance. It was concluded that the HCPEB irradiation could replace the pre-treatment of aluminum substrate as required in conventional electroless plating with a decreased surface roughness of Ni-P alloy plating layer. The plates exhibited an amorphous microstructure as demonstrated by XRD analysis. The plates, produced with the routine of HCPEB irradiation, activation and electroless plating possess, also exhibited good quality, even better than that of conventional electroless plating technique.

Abstract Electron beam modification of carbon black (N220) and carbon-silica dual phase filler affects the microstructure of carbon black. This is confirmed from X-ray diffraction studies. The scanning electron microscopy /energy dispersive X-ray analysis reveals surface oxidation, which is further corroborated from nitrogen and iodine adsorptions. Transmission electron microscopy studies show the aggregation of fillers upon electron beam irradiation. Linear fractal dimension calculated by image analysis increases upon irradiation, due to the formation of filler aggregates.

High current pulsed electron beam (HCPEB) treatment was conducted on 40CrNiMo7 steel. The surface microstructure was characterized by metalloscopy and X-ray diffraction methods. The microhardness and wear resistance of modified surface were measured. After the HCPEB treatment, the surface crater structure was observed due to the inhomogeneity of initial material. A modified layer of depth ~ 7 μm was formed with a hybrid microstructure composed mainly of martensite and a small quantity of austenite. The surface microhardness of HCPEB modified sample was increased drastically to more than 1000 HK. The wear resistance increased by about 36% as compared to the initial state.

The microstructure modifications, phase, and texture formations encountered in a TiAl based Ti48Al2Cr2Nb intermetallic alloy induced by the high current pulsed electron beam (HCPEB) treatment were carefully investigated using scanning electron microscope (SEM), X-ray diffraction (XRD), and electron backscattered diffraction (EBSD) techniques. The initial material contains the majorityγ-TiAl phase and the minorityα-Ti3Al phase. After the HCPEB treatment, the initialα-Ti3Al was dissolved into the melted layer and the very top surface is covered by ultrafine-grainedα-Ti3Al phase having thermal stress induced cracks. EBSD analyses showed thatα-Ti3Al phase on the very top surface has a001//ND fiber texture and its texture intensity increases with the number of pulses. The superfast thermal stress cycles and the selective evaporation induced by the HCPEB treatment account for the microstructure modifications and formations of ultrafineα-Ti3Al in the TiAl based intermetallic alloy.

Electron beam irradiation cross-linking of polyvinyl alcohol (PVA) films with the presence of N, N'- methylene bisacrylamide (MBA) were studied, improving the thermal stability. The films unirradiated and irradiated were characterized by ATR-FTIR spectroscopy, X-ray diffraction, differential scanning calorimetry and thermo gravimetric analysis. The PVA films with the presence of MBA would crosslink after irradiation. The crystallinity increased firstly and then decreased as a function of irradiation dose, while the melting temperature decreased with increasing the dose. Beside, the T30%, T50%, T90% and Tmax temperature of degradation increased as the irradiation dose increased.

A new approach to fabricate TiNi surfaces combining the advantages of both monolithic and porous materials for implants is used in this work. New materials were obtained by depositing a porous TiNi powder onto monolithic TiNi plates followed by sintering at 1200 °C. Then, further modification of the material surface with a high-current-pulsed electron beam (HCPEB) was carried out. Three materials obtained (one after sintering and two after subsequent beam treatment by 30 pulses with different pulse energy) were studied by XRD, SEM, EDX, surface profilometry, and by means of electrochemical measurements, including OCP and EIS. Structural and compositional changes caused by HCPEB treatment were investigated. Surface properties of the samples during their storage in saline for 10 days were studied and a model experiment with cell growth (MCF-7) was carried out for the unmodified sample with an electron beam to detect cell appearance on different surface locations.
