Coating Surface Profilometry Optional. Specimen Flatness and Level. Applications of scratch testing in polymer industry Application Reports en.

The zstm along the scratch track is microscopically assessed as a function of the applied force. Any specimen conditioning asm environmental exposure shall be fully documented in the test report, describing in detail the exposure conditions temperature, atmosphere, pressures, chemistry, humidity, and so forththe length of time, and resulting changes in coating morphology, composition, and microstructure.

The user only needs to set up some threshold values and start the automatic analysis of critical loads Lc. Test specimens generally have a planar surface for testing, but cylinder geometries can also be tested with an c124 fixture. Link to Active This link will always route to the current Active version of the standard. The test method may be applicable to hard metal coatings which fail in a brittle mode with appropriate changes in test parameters and damage analysis procedures and criteria.

In this way the measurement curve can be analyzed exactly parallel to the scratch picture on one page. Please first log in with a verified email before subscribing to alerts. You axtm download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Material and Specimen Related. Thinner coatings may require a smaller diameter stylus and lower normal forces for reliable results.

Rather, the test method gives a quantitative engineering measurement of the practical extrinsic adhesion strength and damage resistance of the coating-substrate system as a function of applied normal force. Experimental Factors and Variables.

Primary and Supplementary Measurements. You may delete a document from your Alert Profile at any time. This standard is not included in any packages. If the document is revised or amended, you will be notified by email. The test method also describes the use of tangential force and acoustic emission signals as secondary test data to identify different coating damage levels.

Coating Adhesion Reference Specimens Optional. Subscription pricing is determined by: Specific levels of progressive damage are associated with increasing normal stylus forces.

By certifying our products accordingly, we can guarantee high-quality products and services aztm terms of safety, reliability, and environmental friendliness. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. We have no amendments or corrections for this standard.

Measurements of the damage mechanisms in a coating as a function of applied normal forces are useful to understand material-process-property relations; quantify and qualify the mechanical response of coating-substrate systems; assess coating durability; measure production quality; and support failure analysis.

Mechanical Stage and Displacement Control.

This unique feature is exclusive to Anton Paar scratch testers. Link to Active This link will always route to the current Active version of the standard. Your Alert Profile lists the documents that will be monitored. Characterization of hard coatings — part I: Test Frame and Force Application System. Need more than one copy?

Summary of Test Method. Other Standards and References.

The critical load data is used to quantify the adhesive properties of different film-substrate combinations by using different sensors acoustic emission, penetration depth, friction force and video microscope observations. The same cc1624 holder can be used for different kinds of tips such as spherical tips 1, 5, 20, Get in touch Document Finder. The test method also describes the use of tangential force and acoustic emission signals as secondary test data to identify different coating damage levels.

Specimen Exposure Conditioning Optional. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Stylus Inspection and Cleaning.

ASTM C1624 – 05(2015)

Commonly, the low comparative modulus of the polymer substrate means that the ceramic coating will generally tend to fail in bending through-thickness c16244 failure before cohesive failure in the coating itself. Experimental Variables in Scratch Adhesion Testing. Test Equipment and Procedure Information. Thicker coatings may require larger diameter stylus and higher normal forces.
