“…This is probably due to the change in the conditions of friction on the rake face of the cutting insert as a result of ion implantation. Similar results were also observed by other researchers (Shalnov et al, 2011;Yang et al, 2007). …”

Abstract:The high-speed steel HS 6-5-2 cutting inserts coated with TiN were subjected to ion implantation with both silicon (dose 2x10 17 Si + /cm 2 ) and silicon with nitrogen ions (dose (1+1)x10 17 (Si + + N + )/cm 2 ) on the subsurface layer of the rake face. Microhardness was examined before and after ion implantation. The composition and structural properties of the subsurface layer were examined by Glow Discharge Optical Emission Spectroscopy (GD-OES). The turning tests of 40H construction steel with the use of the cutting inserts implanted and non-implanted were performed. During the tests the two components of the net cutting force (the main cutting force Fc and feed force Ff) as well as the wear parameters VB on the major flankalong with the surface roughness (Ra) were measured. The implanted inserts exhibited higher durability compared to non-implanted ones.

“…The hardness was increased with Ar implantation, as it is heavier than Nitrogen and can create more defects in the substrate (dislocations hardening). For the friction coefficient decreasing, TiB 2 implantation with the Nitrogen was more effective, due to the nitrides formation effect [22]. Wetting contact angles were significantly increased after the implantations, which is due to the formation of the novel phases in the surface layer (Ti-B/Ti-N, etc.…”

“…The implantation energy in the process was 20 keV and implantation fluence was ~ 5 × 10 17 ions/cm 2 . The implantation provides hardened, wear resistant and chemically different surface layer without noticeable roughness or dimension changes [12,22]. Depth of the surface layer modification for the performed ion implantation was about 10-20 nm.…”

Consideration on Surface Modification of Steel Dies to Reducing the Plastic Sticking in the Forming Process

Plastic parts such as syringe, phone cases, containers, etc. are formed in the mold under the molten temperature and with the high pressure. Plastic sticking to the mold surface during forming process is a serious practical problem for the manufacturing. The sticking limits mold lifetime, reduces production speed and degrades product surface quality. Mold material, surface condition, plastic chemical properties and molding parameters effect on the sticking. In this work, the effectiveness of surface treatments including mechanical polishing, plasma nitriding, hard DLC coating and TiB 2 ion implantation were investigated in regards to reducing the plastic sticking on the steels -SKD61, HPM38 and PX5 surface. The surface finishing was characterized with surface roughness, hardness, friction coefficients and wettability. Adhesion strength of the steel -plastic interface for the plastic materials: polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), poly-butylene terephthalate (PBT) were measured with the developed method, with the concept of real surface area. It was shown that, for the different plastics, the appropriate die material and die finishing must be chosen to provide the lowest plastic sticking.

“…7,9 Previously, the setup, with TiB 2 sputtering target, was applied for the surface properties modification of construction steels and alloys, as well as for the commercial products, such as cutting tools and metal dies. 10 Here, the investigation of the ion-plasma source parameters was performed from the point of view of the effectiveness of target sputtering. Influences of electrodes geometry, ion current density, sputtering, and acceleration voltages were investigated.…”

In the work, investigation of the features and operation regimes of sputter enhanced ion-plasma source are presented. The source is based on the target sputtering with the dense plasma formed in the crossed electric and magnetic fields. It allows operation with noble or reactive gases at low pressure discharge regimes, and, the resulting ion beam is the mixture of ions from the working gas and sputtering target. Any conductive material, such as metals, alloys, or compounds, can be used as the sputtering target. Effectiveness of target sputtering process with the plasma was investigated dependently on the gun geometry, plasma parameters, and the target bias voltage. With the applied accelerating voltage from 0 to 20 kV, the source can be operated in regimes of thin film deposition, ion-beam mixing, and ion implantation. Multi-component ion beam implantation was applied to α-Fe, which leads to the surface hardness increasing from 2 GPa in the initial condition up to 3.5 GPa in case of combined N(2)-C implantation. Projected range of the implanted elements is up to 20 nm with the implantation energy 20 keV that was obtained with XPS depth profiling.
