“…Therefore, single lap shear adhesive bond strength of plasma-treated titanium alloy is comparable to that of chemically modified titanium surface. [16] 1. Atmospheric pressure plasma treatment Polyimide sheets were plasma treated using TIGRES Plasma-BLASTER MEF equipment with operating voltage of 230 V and frequency of 60 Hz.…”

This investigation highlights the effect of surface modification on polyimide by atmospheric pressure plasma treatment with different exposure time. Surface modification of polymer by plasma treatment essentially creates physical and chemical changes such as cross-linking and formation of free radicals. It also forms oxygen functionalization in the form of polar groups on polymer surface, hence improving the wetting and adhesion properties. It is observed that surface energy of the polymer increases with increasing exposure time of atmospheric pressure plasma. However, prolonged exposure time of plasma results in deterioration of the surface layer of polyimide resulting in degradation and embrittlement. Scanning electron microscopy and atomic force microscopy analysis reveal that there is a considerable morphological change on the polymer surface due to atmospheric pressure plasma treatment. X-ray photo electron spectroscopy analysis reveals that the oxygen functionalities of polymer surface increases significantly when polyimide is exposed to atmospheric pressure plasma. Untreated and atmospheric pressure plasma-treated polyimide sheet are adhesive bonded by employing polyimide adhesive as well as with titanium substrate. Due to surface modification of polyimide, it is observed that there is a significant increase in lap shear tensile strength, and therefore, this technology is highly acceptable for aviation and space applications.

“…Elements made of titanium and its alloys used in these industries must very often be joined. It can be observed that titanium elements are more and more widely joined by adhesive bonding, a technique that constitutes an alternative to traditional joining methods [4][5][6][7][8][9][10]. Adhesive bonding is used for joining materials with specified properties, which are then used for making elements of various shapes located in various places of the structure.…”

“…The latter is more frequently used, because in sulfuric acid etching, one can observe hydrogen adsorption by titanium. In addition to this, surface can also be prepared by plasma treatment [8,10,16,22]. Surface preparation of titanium and titanium alloys for adhesive bonding usually involves the use of mechanical treatment [8,15,18,23].…”

This study investigated the effect of the different surface treatment methods on the strength of Ti6Al4V titanium alloy sheet adhesive joints. The following surface treatment methods were used: alkaline degreasing, anodizing, vibratory shot peening, and anodizing with vibrational shot peening. The following tests/measurements were carried out during the experiment: surface roughness measurements; microhardness measurements (conducted by the Vickers hardness test method); and strength tests of single-lap adhesive joints fabricated with the use of two epoxy adhesives, rigid and flexible, both based on epoxy resin Epidian 5. It has been found that the application of anodizing followed by vibratory shot peening leads to increased strength of adhesive joints, irrespective of the type of applied epoxy adhesive.

Abstract.A cathodic stripping voltammetric method for determination of Ti(IV) in water samples containing high concentrations of surfactants is described. The linear calibration plot for Ti(IV) was achieved in the simultaneous presence of 5 mg L -1 anionic, 1 mg L -1 cationic and 2 mg L -1 nonionic surfactants for an accumulation time of 30 s in the range 2.5 × 10 -8 to 5 × 10 -7 mol L -1 , the detection limit for accumulation time of 30 s was about 8.4 × 10 -9 mol L -1 . The developed method was successfully applied to Ti(IV) determination in environmental waters, such as river water (Bystrzyca, Czerniejówka), stagnant water (Lake Zemborzyce) and rain water (collected from eastern areas of Poland) with satisfactory results.
