Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction

Electrolytic codeposition of ceramic particles into the metal matrix is a low-cost and low-temperature

method suitable for producing composite coating. Ceramics particles can be hard oxide or carbides

like Al O , SiC, Si N , TiO , WC or diamond. Also, it may include solid lubricants like PTFE, graphite,

2 3 3 4 2

h-BN or MoS . Incorporation of such particles can improve mechanical, tribological and anti-corrosion

properties of electrodeposited coatings. Nickel being an engineering material, nickel-ceramics composite

coating can find wide application such as cutting tools for semiconductors, heat exchangers, automobile

shackle pin, glass moulds. The applications cover machine elements, tools, electronics, micro-system

technology, electrochemistry, acoustics, decoration and many more. In addition, electrodeposited

nickel-ceramics composite coating can be applied in automotive parts including cylinder bores, piston

and piston rings to increase engine performance. Nickel-based composites exist as many different

types depending upon kind of ceramic particles incorporated, which can differ significantly in their

properties. To increase hardness and corrosion resistance, hard ceramic particles such as SiC, Si N and

3 4

Al O can be used, whereas to increase wear resistance property, mainly self-lubricating solid particles

2 3

such as h-BN, PTFE or MoS can be used. It is therefore important to choose the right ceramic particles

for a given application. Typical solution compositions, operating conditions and mechanical properties

of electrodeposits from Watts and nickel sulphamate solutions are given in Annex B.

The objective of this document is to provide processing and requirements that cover all nickel-based

composite system. This enables both providers as well as users to easily fabricate the composite system.
