The deposit acts as an anode with respect to the basis metal when oxidation occurs. It
protects the base metal.
Zinc plated on steel is an example.

SCATTER DIAGRAM
A scatter diagram is a visual tool for showing the relationship between
two variables.
It shows clearly if there is a relationship, or correlation,
between the two variables:
POSITIVE CORRELATION - as x increases, so does y; NEGATIVE
CORRELATION -
as x increases, y decreases; NO CORRELATION - one quantity has no
particular
relation to the other. It provides the verification of a potential
root cause.

SEVEN BASIC TOOLS of QC
The major use of QC tools is to provide objectivity and clarity. The
tools separate
opinions from data-based logic, thereby allowing anyone to 'speak
with facts.'
The SEVEN TOOLS of QC are : CHECKSHEET, PARETO CHART, ISHIKAWA
or
FISHBONE DIAGRAM, GRAPH, HISTOGRAM, SCATTER DIAGRAM, and CONTROL CHARTS.

SIX-SIGMA
A statistical way of measuring quality, six-sigma is equivalent to 3.4
defects per million units of output-a virtually defect-free level of
performance.
The ambitious, company wide goal of 'SIX-SIGMA QUALITY' has been adopted
by Motorola, a 1988 Baldridge Award winner.

SPC
STATISICAL PROCESS CONTROL
Based on the principle that no two units of output of a process are likely
to
have the exact same specifications SPC involves the mathematical
determination
of acceptable limits of variation. Graphs are used by workers to
plot
output variables and visually determine when a process is 'IN' or 'out of'
control.

SPECIAL CAUSE
An 'abnormal' source of variation that does not arise from the production
process
itself but which is extraneous and unpredictable.
SPECIFICATION LIMITS
Specification limits are determined by the customers' valid
requirements regardless
of what the process is capable of achieving.

SQC
STATISCAL QUALITY CONTROL
A relatively early development in the evolution of the quality discipline,
SQC
relies on statistical concepts and tools ( e.g., sampling techniques
) to control
production quality. SQC techniques are used in TOTAL QUALITY
MANAGEMENT,
although the emphasis in TQM is on 'building quality in,' rather than
error detection.

STANDARD DEVIATION
The STANDARD DEVIATION is a measure of how tightly the data points cluster
about the mean ( average ). It is represented by Sigma ( o-).
The Standard
Deviation is far less sensitive to the addition of another data point or
the changing
of a data point; therefore, it is a more reliable MEASURE OF
THE VARIABILITY of a process.

such as iron, aluminum or calcium.

STRATIFICATION
Stratification is a technique used for breaking down the whole ( total
area of concern )
into smaller, related subgroups. Stratification of information
specifies the data and enables
someone to do a more precise analysis of it. It is a useful
tool for verifying root cause.
STRETCH GOAL
An ambitious usually long-term quality goal that requires
extraordinary effort
innovation and planning to achieve.
STRIKE
Thin layer of nickel or copper over a clean active raw base
metal plated from a
corrosive low-metal content bath; used on stainless steel.
STRIPPING VOLTAMMETRY
An analytical process which measures the applied voltage versus anodic stripping. It
consists of stripping the species
electrochemically until there is a change in voltage.
SUBSTRATE
Any exposed surface of the raw parts to be plated; ( also called
'base' 'base metal' or 'raw part' ).
