“…Four targets, two Cr and two NiCr (Ni/Cr = 80:20 at.%), placed alternatively, were used. A NiCr alloy was used instead of pure Ni to supply Ni because its paramagnetic nature yields better deposition properties [13].…”

CrN is one of the most important transition metal nitrides, used as protective and anti-wear coating in modern engineering applications. However, CrN coatings are typically brittle and susceptible to catastrophic failure. In this paper, CrNiN coatings with differing Ni contents were deposited on tool steel substrates using a closed field unbalanced magnetron sputtering system. The effects of Ni addition on the microstructure and mechanical characteristics of CrN thin films were studied by combining nanoindentation tests with cross-sectional transmission electron microscopy. A columnar structure was observed in the CrN coating. With an increase in Ni content, the resultant columnar grains exhibited a high aspect ratio. Ni additions to CrN were

“…In Fig. 5 it is possible to observe that the percentage of elastic recovery depends on the applied bias voltage or bias current density; showing that the sample with the maximum negative bias voltage presents the maximum percentage of elastic recovery, R, the greater reduced elastic modulus (390 GPa), proportional to the higher hardness (30 GPa) [23,24] (Fig. 5b).…”

“…However no experimental results have been published showing the feasibility of this proposal for replication tools. Navabpour et al (2006) proposed the use of magnetronsputtered coatings to tool surfaces to address the adhesion of low-density polyethylene to molds during processing. The tests described included contact angle measurements (using both liquid and LDPE granules), adhesion tests (using a tensometer) and surface analysis.…”

The demolding of replicated parts can result in damage to both the replication tooling and finished parts and is a particular problem for the replication of smaller parts which can be quite fragile. Various techniques have been proposed in the literature to solve such problems by reducing the overall demolding force. This paper presents the challenge of demolding replicated parts and reviews the proven solutions from the literature which have been developed. A summary chart of these solutions is presented which may be used to implement plans to solve demolding problems with replicated parts. Such a rationalization of existing knowledge will enable replication tool developers to systematically select and apply proven solutions to solve, and ultimately prevent, demolding problems.
