Tenders are invited for tender for supply and installation of thickness profilometer
in the department of electronics engineering, iit (bhu), varanasi.
To determine the minimum mold opening time required of molded IMC parts in a more quantitative way, at each molding temperature, the surface quality of molded parts was evaluated by using a Wyko NT9100 optical profilometer
(Bruker AXS Inc.).
Mean surface roughness (Ra) of the specimens were analyzed by a tactile profilometer
(Taylor Hobson Surtronic 25, Leicester, UK) initially and after polishing with a 0,25 mm cut-off value.
In this study, a stylus-type surface profilometer
(Surfcom130A, Mitutoyo) was used for the measurement of arithmetic average of surface roughness (Ra) on the resultant machined surface.
To measure the roughness of the surface, a profilometer
, Surtronic 3P, was used with a cutoff equal to 2.5 mm.
To assess the validity, a microstep (surface gold-plated, a testing sample of Lyncee tec) was measured by the setup of DDHM, and a stylus profilometer
(KLA-Tencor, P-16 +/P-6) with the force of 1 mg for comparison.
Surface roughness results were measured using a contact profilometer
. There was a significant improvement in surface smoothness from the three-screen 44 GFN silica to the four-screen 67 GFN silica.
Preparations were blotted dry and initial measurements taken with a surface profilometer
(Mitutoyo Surftest SJ-210) to determine baseline surface roughness.
Surface roughness measurement with the help of surface profilometer
revealed that samples treated with blasting with alumina (50[micro]) blasting followed by acid etching with 2% hydrofluoric acid showed the highest mean roughness value.
The latest evolution of WITec's TrueSurface advanced optical profilometer
enhances the power and user-friendliness of confocal Raman microscopes.
The thickness of the coatings and the surface roughness was measured with a stylus profilometer
Veeco Dektak 150 3D.
The surface roughness of porcelain was measured with a noncontact optical profilometer
. For each porcelain sample, two readings were taken across the sample, before porcelain surface treatment (T1) and after porcelain surface treatment (T2).
