Journal of Materials Research, 2007
For a number of polymers with a variety of chemical structures and different properties, we have performed scratch-resistance tests and investigated the profiles of the grooves formed using a profilometer. Three main kinds of material response are seen: plowing; cutting; and densification. The cross-sectional areas of the grooves include the groove and

The scratch test for determining the susceptibility of a person to diphtheria differs from the well known Schick test 1 in that the method is not intracutaneous but cutaneous. The test is therefore performed and read in the same manner as the Pirquet test for tuberculosis, 2 except, of course, that diphtheria toxin instead of tuberculin is used.

The Reliability of the “Scratch Test”
Journal of Hand Surgery (European Volume), 2008The “Scratch Test” uses a sharp scalpel to scrape areas of suspected tendinosis in the management of lateral and medial epicondylitis. As claimed in the literature, this tissue is friable and peels off, whereas normal tendon does not. The purpose of this study was to determine whether, or not, the “Scratch Test” is able to differentiate between ...

SPIE Proceedings, 1986
During its use, a spectacle lens is subjected to numerous different abrasive conditions (e.g. cleaning ; wipping) which make two types of surface scratches : Viscoelastic and brittle scratches. We present here a scratch testing machine (rayoscope) and a scratch diamond test which allows to reproduce these two kinds of scratches and to caracterize the ...

Friction monitored scratch adhesion testing
Surface and Coatings Technology, 1995Abstract During a scratch adhesion test, the plot of the frictional force against the normal applied load on the diamond can indicate different types of failure: small oscillations in the measured friction correspond to chipping, bigger variations show the presence of flaking.

Annals of Plastic Surgery
Introduction Carpal tunnel syndrome is commonly managed by hand and upper extremity surgeons. Though electrodiagnostics are considered the gold standard diagnosis, the scratch collapse test (SCT) was introduced to address uncertainty, despite remains controversial. To address this, we sought to identify if the SCT can correlate

Scratch Testing of Nanostructured Films
World Tribology Congress III, Volume 2, 2005Nanostructured films offer potential for considerable improvements in mechanical properties by comparison with traditional single composition coatings. This nanostructuring can be carried out in many ways, but one of the easiest methods to implement it is through nanolayering with two or more phases.

The scratch collapse test: A systematic review
Journal of Plastic, Reconstructive & Aesthetic Surgery, 2018The diagnosis of nerve compression relies on collecting diagnostic clues from the history, physical examination, imaging and diagnostic testing. There are several provocative tests to aid in the diagnosis of nerve compression. The 'Scratch Collapse Test' (SCT) has emerged as a new provocative test to assist in the localisation of peripheral nerve ...

Scratch Adhesion Testing: A Critique
Surface Engineering, 1986The method of testing the adhesion of a thin, strongly adhering film by scratching it with a loaded diamond stylus is currently the only really satisfactory test available. In this paper the critical load for coating loss and the accompanying so called acoustic emission are discussed critically, together with aspects of metallurgical interest.

Scratch and indentation tests on seashells
Tribology International, 2009Abstract In this work, the scratch and indentation properties of the outer and inner (nacre) layers of green mussel shells under dry and water-soaked conditions were investigated. In micro-scratch tests with increasing normal load, it was found that the scratch hardness of the inner and outer shell surfaces tended to decrease rapidly at lower loads ...
