Data about bulk properties of Ti-6Al-4V based composites specimen achieved by powder metallurgy route using spark plasma sintering (SPS) technique is presented, with focus on the effect of TiN particles on wear and corrosion behavior of the resultant composites. Two microsized kind of powders are combined; Ti-6Al-4V and TiN. The powder mixing and SPS processing has been enhanced and consolidated.  Data was attained from spark plasma sintered composites. The powders were tubular mixed for 4 h subsequent to spark plasma sintering process.

Experimental features
Following to polishing, compacts were experimented through SEM-EDS, Anton paar wear tester, XRD, hardness and corrosion tests were done to determine the mechanical, corrosion and wear properties of the spark plasma sintered composites.

Data source location
Tshwane University of Technology Laboratory, Pretoria,South Africa Data accessibility All the data are in this data article.

Value of the data
This data could be used to further improve wear and corrosion properties of Ti-6Al-4V alloy for various applications including aerospace.
The data could be used to determine the optimal TiN addition necessary to achieve enhanced properties of titanium made components.

Data collection
Microsized Ti-6Al-4V-xTiN powders have been blended via spark plasma sintering method [1,4]. Density measurements, hardness, corrosion, SEM-EDS, and XRD data of the samples are presented. The wear properties of the fabricated specimen are presented.

Data analysis and presentation
Microsized titanium powder (Ti-6Al-4V) of (45-90 mm particle spherical, from TLS Technik GmbH) and titanium nitride powder (TiN) of ( o3 mm particle size from sigma Aldrich) were provided    Table 1, and the powders were considered in different quantities as presented in Table 2.
Three samples with varying titanium nitride amounts from 5-15 wt% were set and mixed in a tubular mixer preceding to further process. Spark plasma sintering method using SPS FCT Systeme GmbH Rauenstein model was employed [1,2,4]. Ideal operational parameters were used. Sintering temperature was 1000°C, pressure 50 MPa and the holding time 6 min under argon atmosphere [3].   Fig. 2(a)-(d). Fig. 2(a) displays the SEM-EDS of the spark plasma sintered Ti-6Al-4V alloy. The morphology of the reinforced Ti-6Al-4V alloy composites are revealed in Fig. 3(b-d) [6]. Fig. 4 illustrates relative densities of the sintered compacts [6]. Microhardness trend of the spark plasma sintered compacts can be observed in Fig. 5. Fig. 6 shows the XRD patterns of Ti-6Al-4V alloy obtained from spark plasma sintering of with and without TiN at the sintering temperature of 1000°C and holding time of 6 min. Fig. 7 shows coefficient of friction traces for Ti-6Al-4V and Ti-6Al-4V-xTiN composites. Fig. 8 shows the volume loss of the samples after sliding distance of 4 m at normal load of 10 N. Corrosion properties of spark plasma sintered (SPS) Ti-6Al-4V-TiN were explored in 3.65NaCl containing 0.1 M HCl media with the help of potentiodynamic polarization technique [5]. The polarization resistance of the developed compacts is shown in Fig. 9 and Table 3.
