Effects of Nitrogen Ion Implantation in 304 Stainless Steel at High Temperatures. (1998)
Shrivastava, Sadhna, Tarey, Ram D., Bhatnager, M. C., Jain, Amitabh, Chopra, K. L.
THE EFFECT OF VARYING THE TARGET TEMPERATURE (BY CHANGING THE BEAM POWER) ON THE STRUCTURE AND PROPERTIES OF NITROGEN ION IMPLANTED 304 STAINLESS STEEL WAS STUDIED; WITH A BEAM POWER OF 0.1 W/SQ.CM...
Shrivastava, Sadhna, Tarey, Ram D., Bhatnagar, M. C., Jain, Amitabh, Chopra, K. L.
Nitrogen ion implantation has proved effective in the surface strengthening of metals and alloys. In order to achieve high throughputs industrially, high beam currents must be used. The resulting...
Isostatic Compaction of Silicon Carbide Reinforced Aluminium. (1998)
Sagar, R., Madan, P. K., Kumar, Mukul, Sachdeva, S., Jain, Amitabh
The processing and mechanical properties of a compact made from commercial grade aluminium powder that has been reinforced with sic particles have been investigated. mixtures of four compositions...
The Sliding Wear of Titanium Nitride Coatings. (1998)
Bull, S. J., Rickerby, D. S., Jain, Amitabh
Although the mechanisms by which titanium nitride (TiN) coatings can affect the abrasive wear resistance of coated components are well documented, relatively little is known about the sliding wear...
Toughening of thin films by high energy ion beams (1996)
Jain, Amitabh, Loganathan, S, Jain, Uma
Refractory metal films tend to grow with a high degree of intrinsic tensile stress. As the film thickness increases, the integrated stress becomes high enough to cause loss of adhesion. In the...
Sliding Behaviour of Boron Ion-Implanted 304 Stainless Steel (1995)
Shrivastava, Sadhna, Jain, Amitabh, Singh, Chatar
We have studied the influence of boron ion implantation on the friction and wear behaviour of 304 stainless steel. We find an increase in microhardness following implantation. We also observe a...
A Physical Basis for Irradiation-Induced Modification of Thin-Film Stresses (1995)
A mechanism is proposed for the modification of stresses in thin films by irradiation. A tensile stress causes preferential alignment of interstitial loops such that the normal to the plane of the...
A physical basis for stress reduction during ion beam assisted deposition (1995)
Deposition of thin films and ion implantation in solids have been actively pursued as a means of enhancing surface properties. Conventional thin films often suffer from stresses which limit their...
High energy heavy ion irradiation of chromium films (1995)
Jain, Amitabh, Loganathan, S, Kanjilal, D, Mehta, G K
We have studied the modification of chromium coatings by nickel ion beams at a high energy (75 MeV) so that the range of the ions is many times the film thickness, which is of the order of 7 pm. At...
Jain, Amitabh, Shrivastava, Sadhna
We have investigated the effects of boron ion implantation on the wear behaviour of 304 stainless steel. The initial phase composition of the specimens was varied by using two different kinds of...
Srivastav, Sangeeta, Jain, Amitabh, Kanjilal, D
The performance of tribological coatings depends greatly on the adhesion of the coating to the substrate. Various techniques are known for surface modification. Ion irradiation is a technique which...
Evaluation of oil samples from centrifugal separators (1993)
Jain, Amitabh, Biswas, S, Shrivastava, Sadhna, Jagga, C R
The cleanliness of lubricating oil in plant equipment is of prime concern since particulate contamination can lead to undesirable wear. It is important to be able to measure the size distribution of...
